A201, A251 Size 9 2 and 3 Pole Contactors, Non-reversing and ReversingFig. 1 Front Connected 3 Pole ContactorFig. 2 Rear Connected 3 Pole ContactorFig. 3 Dimension Drawings (Dim. in inches)Size 9 Contactors are designed for the control of inductive or non-inductive loads at voltages between 24 and 600, AC. The units are suitable for mount-ing on either steel or insulated panels. All parts are front removable. Contac-tors should be protected against short circuits by branch circuit protective devices selected in accordance with the National Electrical Code (NEG).Two pole contactors have the same current ratings as 3 pole devices but are not suitable controlling 3 phase motors.This industrial type control is designed to be installed, operated, and main-tained by adequately trained workmen. These instructions do not cover all details, variations, or combinations of the equipment, its storage, delivery, installation, check-out, safe operation, or maintenance. Care must be ex-ercised to comply with local, state, and national regulations, as well as safety practices, for this class of equipment.CONTACTOR RATINGS - 3 POLE CONTACTORS Continuous Current Three Phase Horsepower at:Open 2500AEnclosed 2250A230 Volts 800460 Volts 1600Three Phase Switching at:T ransformers Capacitors 208 Volts 240 Volts 480 Volts 600 Volts337 KVA 392 KVA 783 KVA 975 KVA575 KVAR 655 KVAR 1325 KVAR 1670 KVARCONTACTOR RATINGS - 2 POLE CONTACTORSSingle Phase Switching at:T ransformer Rating120 Volts 240 Volts 480 Volts 600 Volts112 KVA 225 KVA 450 KVA 562 KVAA201 And A251, Size 9 Contactors Coils.Each size 9 contactor has a single winding ,DC coil rated such that it canbe supplied from a full wave rectiﬁer operating at 120 volts AC. As theoperating magnet armature approaches its sealed position a late-break,normally-closed auxiliary contact opens and introduces a resistor into thecoil circuit reducing the voltage across the coil to approximately 17 voltsDC. See Figures 4 and 5 for control circuits. The control relays (CR) shownin Figures 4 and 5 are not included with the contactor. The 120 volt, 60hertz control power transformer or separate supply must be capable ofsupplying 2100 VA inrush and 350 VA (350 Watts) continuously while main-taining an AC voltage of not less than 115 volts to the rectiﬁ er, in additionto supplying control relays and other control circuit devices such as indicat-ing lights. Overcurrent protection for the control circuit (#12 AWG) shouldbe provided at the source of control voltage in accordance with the NEC.The coils have been designed to operate at high temperatures, and areinsulated to meet such service. The operator should not be alarmed to ﬁ ndthe coils hot to the touch.Changing Coils.To remove and replace the operating coil, proceed as shown below. Item( ) references are to Fig. 6. Tightening torque values are shown in Table 1.1. Turn all power OFF.2. Remove the arc quencher (1) adjacent to the coil.3. Remove the coil (2) leads and adjacent phase barrier (3).4. Remove the two screws holding the auxiliary contact support bracket(4) to the lower horizontal brace. Let the attached leads support theauxiliary contact assembly (5).5. Remove the armature stop (6), magnet pole face (7), shim retainer(8), and stop bracket (9), by removing the five 1/2-13 cap screws andtwo spacers (10). The armature (11) can now rotate out of the way tofacilitate coil removal from the magnet core.6. Replace the coil.7. Remount the retainer, shim and pole face, ensuring that the shim islocated between the magnet core and the pole face. Tighten the capscrew holding the pole face to the core.8. Attach the armature stop bracket and shorter spacer to the left sideof the pole face. Insert the longer spacer between the pole face andend plate. Rotate the armature forward and attach the armature stop.9. Torque the five cap screws to 100 pound-feet.10. Reattach the auxiliary contact assembly to the lower brace.11. Attach the coil leads.12. With the power circuit disconnect open, energize the coil circuit.13. Check to confirm that, with the armature sealed:(a) The armature is centered on the pole face within 1/32 inch.(b) There is approximately 1/16 inch clearance between the armatureand lower pole face.(c) The electrical interlocks’ plunger can be depressed an additional1/16 inch before bottoming out.Loosen and adjust parts as necessary.14.

Contact replacement is necessary when the contactovertravel, measured at point X, Figure 7, has been reduced to 3/32 inch.1. T urn all power OFF .2. Remove arc quenchers (1) and phase barriers. (3)3. Remove moving contact shunt bolts (12).4. Remove clamps (13) holding moving contact assembly to the shaftand remove assembly from shaft.5. Remove stationary contact bolts (14).6. Install new stationary contacts and bolts. Refer to Table I for boltdriving torques.7. Install new moving contact assembly on the shaft and bolt shuntends to contacts.8. See page 4 for contact adjustment.9. Replace arc quenchers and phase barriers.Operation And Maintenance.The arc quenchers must be in place when the contactor interrupts a circuit.Each arc quencher is held in place by two screws located at the top. Two pins projecting from the stationary contact support engage notches in the lower rear sides of the arc quencher and serve to position it. A notch mold-ed in the arc quencher cap engages the support plate to hold the arc box in position while the two screws are being assembled. The legs of the arc quencher grid plates are protected from the arc by ceramic barriers, which must be in place when the contactor is operated.Reversing Contactors.Reversing contactors consist of two contactors with power poles intercon-nected by buswork, normally-closed electrical interlocks, and a Type M-52 mechanical interlock.Fig. 6 Cutaway View3Instructions Leaﬂ et IL16978Effective October 2011A201, A251 Size 9 2 and 3. PoleContactors,Non-reversing and ReversingEATON CORPORATION A201 And A251 Size 9 Contactors.Mechanical InterlockThe Type M-52 mechanical interlock is used when a pair of contactors must be mechanically protected against the closing of one when the other is already closed. The two contactors may be exactly alike or may be mixed as to size or number of poles. They must be mounted one below the other, as shown in Figure 3.The Type M-52 mechanical interlock consists of a lower operating lever, a tie rod, and an operating pin secured to the top of the armature of the lower contactor and to the bottom of the armature of the upper contactor. With the upper contactor open and the lower contactor closed, adjust the tie rod so that the lower operating lever clears the operating pin by 1/4 inch. Tighten the tie rod lock nuts. Then make sure, by alternate manual closing of ﬁ rst one contactor, then the other, that interlocking action is correct.Auxiliary Contacts - L64Two double-circuit L64 auxiliary contacts (electrical interlocks) are supplied with each contactor in addition to the normally-closed, late-break contact that introduces resistance into the coil circuit. One normally-open circuit can be used in the coil holding circuit of the control relay that supplies voltage to the contactor coil and one normally-closed circuit can be used for electrical interlocking. The second double-circuit auxiliary is available for circuit monitoring.Contact Adjustment.Make sure that all contact pairs touch simultaneously within 1/32 inch. Sufﬁ cient adjustment can generally be obtained by a selective tightening of the two bolts securing the shaft clamp (13) to the moving contact bracket (Figure 7), tightening one more than the other to produce a slight rota-tion of the assembly on the shaft (17). When adjusted, the contact air gap should be 3/4 inch with the armature in the fully open position. A gap of 3/16 to 7/32 inch, measured at Point X, Figure 7, is typical with newly in-stalled contacts when the armature is in the fully closed position.Contact Spring Forces.Measure the contact force at the top of the moving contact inlay and in line perpendicular to the moving contact (15). The contactor employs multiple contacts in parallel for each pole. The forces given below are for each con-tact. See Figures 6 and 7.To measure the initial force; exert a measured pull with the contactor open until the shank of the moving contact just leaves its stop.To measure the ﬁ nal force, keep the armature (11) fully seated against the magnet pole face (7) and exert a measured pull until the contacts just startto separate. Contact forces with new contacts should be as follows:L64 CONTACT RATINGS(1 normally-open, 1 normally-closed) - A600Part Number Volts Make Break843D943G0424-120 AC120-600 AC24-600 DC60 A7200 VA200 VA6 A720 VA200 VATABLE I RECOMMENDED DRIVING TORQUELocation (Qty.)Driving T orque(LB/IN)Fig. 6Item NumberWire LugsLug Mtg.
