With all three fuses in place and operating properly, this status output has a high resistance value of greater than ten mega-ohms. When one or more of the fuses are open, the status output becomes turned-on with a resistance value less than 35 ohms. This status output withstands voltage (ac or dc) up to 35V at off-state and conducts current up to 40 milli-amps at on-state.Applying voltage and current exceeding these limits will result in damage to the components inside this statusoutput device permanently. There is some time-delay when the status output changes on/off state. The open fuse communications or status output device includes optical isolators within the unit.Communications output states:Fuse Good NO - High Resistance, >10 megohms Opened Fuse NC - Low Resistance, < 35 ohmsOPEN FUSE INDICATIONNote: Operating this device beyond the above limits willcause permanent damage to the components on the board.For applications requiring status output below a system voltage of 460V, contact Bussmann.The examples shown below illustrate typical interface toProgrammable Logic Controllers.STATUS OUTPUTTTL Digital InputPC / PLCVcc (5V to 35V)Pull up Resistor (> 1K)EXAMPLE 1: DIRECT INTERFACE TO PC/PLCPC / PLC EXAMPLE 2: INTERFACE TO PC / PLC WITH OPTICAL ISOLATIONCurrent-Limiting ResistorOptical IsolatorTTL Digital InputVcc (5V to 35V)ISOLATED AC OR DC POWER SOURCESTATUS OUTPUTPull up Resistor (> 1K)Note: When energized (switch in the “on” position), a low load terminal voltage willbe present when fuses are open or when pullout module is removed.

Page 137HM | MOTOR PROTECTORSHERMETICALLY SEALED ON-WINDING, 3-PHASE SPECIFICATIONSFeatures and BenefitsIntroduction• Protect WYE (Star) wound 3-phase motors from 1 to 6-7HP. Used in refrigeration compressors, submeersible pumps and other restrictive environments.• In-line protection in a small, rugged, welded construction. Low profile shape allows for close coupling to motor windings.• Klixon® snap-action discs assure positive make and break action and controlled temperature differential.• Designed for low and high side pressure applications.This protector is designed to protect 3-phase refrigeration and air conditioning compressor motors from excessive winding temperature; however, applications may be made to any WYE wound 3-phase motors where environmental conditions require a hermetic seal. The low profile permits the device to be installed directly on motor windings for closely coupled temperature monitoring, thus enhancing over-temperature protection against loss of refrigeration charge, low voltage locked rotor, and single-phasing (loss of phase). The 37HM is designed to reduce installation costs by replacing pilot control systems with a simple, economical, compact device.The basic element of the 35HM is the famous Klixon® Snap Acting Disc.Maximum Recommended Locked Rotor CurrentCurrent ratings are based on life test data which has demonstrated high reliability at 0.7 power factor on Sensata test boards.

The mechanical interlock holds one or more circuit breakers tripped (prevents closure) when others are closed. A lever assembly is mounted on each breaker that interfaces with the pole shaft and the tripper bar. The lever assemblies are interconnected with cables. Cables can be used for any orientation of the breakers.Required tools• 10 mm socket and 1/4 in drive socket• 10 mm open-end wrench• 11/16 in open-end wrench• 3/8 in open-end wrench• 0.5 mm feeler gauge• 4 mm Allen T wrench• Drive extension Kit parts identificationRefer to Figure 1 and Figure 2 for a visual identification of the parts listed below for the different kits.Kit 1 (Figure 1): Interlock kit parts to mount to breaker.

Closing two breakers holds the third one tripped. Refer to T able 1 on Page 4.(K)(L)(N)(M)Figure 2. Contents of Kit 2A11858G01–04Section 2: Installation of two-waycable interlockProceed with the following 11 steps:Step 1e: Remove the front cover by unscrewing the hex head captive bolts (four for three-pole, six for four-pole) that join the cover to the breaker housing using a 10 mm 1/4 in drive socket. Then hold the charge handle down approximately 45 degrees to pull off the cover.Figure 3. Step 1Step 2e: Remove the knockout from the right side of the front cover using pliers to break out the U-shaped tab. Carefully file any excess material from broken edge.Figure 4. Step 2Step 3e: Install the drive arm (E) to the right end of the pole shaft with the drive arm lever extending downward as shown. Use an M6 x 25 mm flat-head screw (B) to make the connection and torque to 65 in-lb to 85 in-lb (7.3 Nm to 9.6 Nm).Figure 5. Step 33Instructional Leaflet IL2C13864H01Effective January 2014Three-way cable interlock for Magnum fixed circuit breaker (Type 32 interlock)eaton Step 4e: Reinstall front cover removed in Step 1.Step 5e: Attach the interlock assemblies (G) and cable brackets (K) to the mounting plates (J). The interlock assembly is attached to the mounting plate using three M6 x 12 hex bolts (A) and lock washers (C). Torque to 40 in-lb to 50 in-lb (4.5 Nm to 5.6 Nm). Fasten the cable brackets to the mounting plates using two M6 x 10 thread-forming screws (M) and lock washers (L). Torque to 65 in-lb to 85 in-lb (7 Nm to 9 Nm).Figure 6. Step 5Step 6e: Attach the interlock assemblies from Step 5 to the right side of the breakers. Start by removing the M6 hex bolt, nut, lock washer, and grounding (earthing) wire installed in the lower front corner of the mounting foot. This bolt assembly will be reinstalled through the adapter plate near the end of this step.Slide an M6 square nut (F) into the slot in the upper rear part of the case with the flat face toward the outside. The nut may have to be tapped to fully seat it into the slot. Install an M6 x 20 hex bolt (D), lock washer (C), and flat spacer washer (I) into the square nut a few turns. Locate another captive square nut into a slot in the upper part of the case, forward of the square nut just installed. Install another M6 x 20 hex bolt, lock washer, and spacer washer combination in this square nut. Slide the spacer washers fully against the case and the lock washers fully against the heads of the bolts. This creates a space into which the open slots in the top of the mounting plate will slide.Now insert the mounting bracket slots onto the upper bolts and rotate the bracket down against the side of the breaker. Make sure that the drive paddle slides in behind the wireform tripper bar, and the follower arm slides in behind the drive arm pin.Reinstall the lower front bolt assembly (removed earlier), making sure to reconnect the ground (earth) wire. Tighten the upper bolts to stabilize the plate. Now insert an M6 x 12 hex bolt and M6 lock washer through the rear plate and mounting foot, retaining it with square nut on the inside of the mounting foot. Torque to 65 in-lb to 85 in-lb (7 Nm to 9 Nm).Check the interference of the lever assembly to the breaker toensure that flapper arm is behind tripper bar, and follower is BEHIND drive arm pin. If not, remove adapter plate and reinstall properly. Check clearances between end of drive arm and end of follower (1 mm to 4 mm). The tip of the pin on the end of the drive arm should protrude slightly beyond the follower. If this condition is not observed, it may be necessary to adjust the position of the mounting bracket relative to the breaker using upper spacer washers.Figure 7. Step 6Step 7e: At this point in the process, check the functioning of the lever assemblies of each breaker by performing the three following checks in conjunction with provided graphics:Check 1e: With the breaker OPEN and CONNECTED, observe the position of the lower drive lever on each breaker. The gap between the lower right-hand corner of the drive lever and the mountingbracket flange should be from 0 mm to 2 mm (see Figure 8 Breaker OPEN). Now CLOSE the breaker. The drive lever should rotate 60 degrees counterclockwise. There should be a minimum gap of 1 mm and a maximum gap of 4 mm between the lower left-hand corner of the lever and the mounting bracket flange (see Figure 8 Breaker CLOSED). If either of these gaps are out of specification, the installation should not continue . Consult Eaton for additionalinstructions.Figure 8. Step 74Instructional Leaflet IL2C13864H01Effective January 2014Three-way cable interlock for Magnum fixed circuit breaker(Type 32 interlock)eaton Step 8e: This step describes how to route the cables. Beforeinstalling the cables, however, check to be sure that all cables move freely in their cable housing. Route the cables between cassettes in such a fashion that there are no sharp bends in the cable housing and the total number of bends are minimized. The minimum allowable cable housing bend radius is 4 in (102 mm). Aftercompleting the installation and adjustment of the cables, attach the cable housing to the structure at a suitable number of points along the cable run, being careful not to compress the cable housing. The use of plastic wire clamps or wire ties will minimize the likelihood of binding the cables. After the cables are installed, recheck to be sure that the cables still move freely. Refer to T able 1 and Figure 9 for installation details.T able 1. Step 8 Cable Routingtype 32 (six cables)from cassette/fitting to breaker/fitting 1A 1C 3D 2B 2A 2C 1D 3B 3A 3C2D 1BFigure 9. Step 85Instructional Leaflet IL2C13864H01Effective January 2014Three-way cable interlock for Magnum fixed circuit breaker (Type 32 interlock)eaton Step 9e: This step describes how to attach the cables to the interlock assembly and illustrates the attachment of the driven (long rod) end of the cable. Remove nut and spacer tube from the end of the rod. Slide the rubber boot toward the tip of the rod. Unthread the outer bulkhead nut and slide the nut and lock washer toward the tip. Insert the threaded end of the rod into the swivel fitting whilesimultaneously sliding the smaller diameter portion of the bulkhead fitting into the slot in the mounting plate. Raise the cable assembly until the threaded portion of the bulkhead fitting enters the slotted hole and fasten the bulkhead washer and nut finger tight. Adjust the two bulkhead nuts so that the fitting is approximately centered on the cable mounting bracket and hand tighten the nuts. Slide the rubber boot back into place over the end of the bulkhead fitting. Replace the tube spacer and upper nut on the rod end. The lower nuts should be shouldered against the end of the thread and the upper nuts tightened against the spacer tube. While holding the lower nuts, torque to 30 in-lb to 40 in-lb (3.3 Nm to 4.5 Nm). Repeat this process to attach the other end of the cables to the other breaker interlock assembly. See Figure 9 for number and mounting position of cables.The only difference is that the drive (short) rod uses a compression spring. Locate compression spring for Position A below the swivel fitting. The compression spring for the Position C must be located above the swivel fitting (see Figure 10). Therefore, the spring for Position C must be removed before installation and replaced as shown before the installation of the upper rod nut.otee:N Hold the cable rod with pliers while removing and installing the nuts to prevent the cable from rotating.Figure 10. Step 96Instructional Leaflet IL2C13864H01Effective January 2014Three-way cable interlock for Magnum fixed circuit breaker(Type 32 interlock)eaton Step 10 This step describes how to adjust the cables(see Figure 10 and Figure 11 for details). The initial adjustments are made with all breakers OPEN. The bulkhead nuts for each cable should be set so that they are approximately midway on the threaded bulkhead fitting (see Figure 10). The bulkheadnuts should not be moved anymore. Check if all endplates are in the horizontal position and if there is a 1 mm gap as shown in Figure 11 A . To adjust the endplates correctly, use the upper cable nuts above the spacer tube. Check the function of the mechanical interlock assembly according to the logic table (T able 2) onPage 7. Further adjustments (if necessary) can be done by using the bulkhead nuts. Adjust the upper cable nuts again so that all endplates are in the horizontal position. Check the function of the mechanical interlock assembly again according to the logic table (T able 2) on Page 7. Keep adjusting the interlock assembly until it functions correctly. Once the adjustment is completed, the bulkhead nuts and the upper cable nuts can be secured to ensure safety by applying sealing wax.Figure 11.

三相电机过载保护继电器用户手册V1.02
1.性能指标
1.工作环境：温度0～50℃，湿度﹤85%RH的无腐蚀性气体场合；
2.电流输入：三相10A（1~10A）或1A（0.1A~1A），采用用CT隔离、直接穿芯方式；
3.输出方式：一路继电器输出（常闭接点），容量大于5A/250V AC。
4.电流设定范围：1~10A或0.1~1A。
5.工作电源：20-30V AC/DC；功耗：小于3W；
6.绿色LED：运行状态指示灯(指示灯快闪频率约为3次/秒，慢闪频率约为1次/秒)。
a运行状态指示灯常亮：表示电机未工作。
b运行状态指示灯快速闪烁：表示电机
处于起动过程。
c运行状态指示灯慢速闪烁：表示电机正常运行。
7.红色LED：报警指示灯
a报警指示灯快速闪烁：表示电机电流过载。
b报警指示灯常亮：表示电机起动过
程中发生“启动超时”或者“缺相”脱扣，或是电机运行过程中发生“电流过载”
或“缺相”脱扣。
2.设置说明
三相电机过载保护继电器（以下简称装置）采用32位微电脑为核心芯片，配置一个带刻度的调节旋钮，通过旋钮设置电流限值，实时监测电机电流情况，并对异常情况进行脱扣保护处理。
正常使用前请将旋钮调整至合适范围，整定好过载保护动作电流值，如下图所示：
图一10A型过流整定旋钮图二1A型过流整定旋钮如上图一所示，过流整定旋钮调整至5A位置。
1）当电机处于正常运行状态时，电机电流超过5A且持续10秒以上，装置脱扣继电器会动作，断开电机控制回路使电机停机。
2）当启动电机时，电机的启动电流超过5A且持续30秒以上，装置脱扣继电器会动作，断开电机控制回路使电机停机。
注：脱扣后需要执行复位操作，电机才能正常工作。
过载保护只会在电机运行过程中才会投入。
一些重载起动的设备，可根据实际情况适当调高过载保护的整定值，既保证电动机安全运行，也防止出现误动的情况。
列如：现有一台正常运行额定电流值为5A的三相异步电动机，可选择AIX-10A型号的三相电机过载保护继电器，整定的过流限值为5.5A~6.5A。
3.保护功能
三相电机过载保护继电器系列产品主要分为启动超时保护，过载保护，缺相保护三大功能。
1.启动超时保护：电机启动时，启动持续大电流时间超过30S，将对电机进行脱扣停车处理；防止电机在异常启动过程中持续大电流造成的过热和绝缘降低从而烧坏电机。
2.过载保护：电机运行时，当任意相电流持续超出10S后将对电机进行脱扣停车处理；主要保护电机长期运行在额定电流以上，而造成的过热和绝缘降低从而烧坏电机。
3.缺相保护：电机启动或电机运行时，电路中任意一项电路断路后，将对电机进行脱扣停车处理；防止电机在缺相过程中持续大电流造成的过热和绝缘降低从而烧坏电机。
4.复位功能：发生报警后，即报警指示灯常亮时；按下复位键一次，执行设备复位操作，复位完成后报警指示熄灭。
