Finger-safe power distribution blocksCatalog symbol:• PDBFS_Description:The small footprint, high Short-Circuit Current (SCCR) Bussmann™ series power distribution blocks provide IP20* finger-safe protection under specified conditions. These UL® Listed, single-pole blocks are of a modular design that permits dovetailing together the required number of poles for an application and still meet the UL 1953 minimum 1” and 2” spacing required per UL 508A for feeder circuit applications and per NEC® for field installations.With SCCRs up to 200 kA, these blocks help achieve compliance with National Electrical Code (NEC) and OSHA requirements by resolving a common SCCR “weak link” in industrial control panels.To increase application flexibility, these blocks feature dual-wire rated ports that accept copper or aluminum conductors while retaining a UL Listed status.With panel or 35 mm DIN-Rail** mounting for application flexibility these blocks are suitable for installation in wireways and industrial control panel feeder and branch circuits.* See table on page 5.** PDFFS504 panel mount only.Catalog number example:PDBFS204 is a 1-pole blockWhere:• The catalog symbol “PDBFS” defines the block as a finger-safe design.• The catalog number ending “204” in this example defines this block’s lineside and loadside characteristics covering the ampacity, number of ports and wire sizes, etc.• See the catalog number table for details on the available lineside/loadside characteristics.How to order:From the catalog number table, select the catalog number that defines the desired lineside/loadside port and conductor characteristics.Order one block per pole for the application. Multiple single-pole blocks can be ganged together via the dovetailing feature to form multi-pole configurations.Specifications:Ratings• Volts:• 600 V (UL)• 690 V (IEC)• Amps: 175 to 760 A• SCCR: Up to 200 kA (see table for circuit protection details)Agency information• UL 1953 Listed, Guide QPQS, File E256146• CSA® Certified, Class 6228-01, File 47235• RoHS compliant• CEFlammability rating• UL 94 V0Storage and operating temperature range • -4°F to 248°F (-20°C to 120°C)Conductors†• Stranded 75°C copper and aluminum• Higher temperature rated conductors permitted with appropriate derating† As specified in the catalog number table.2Technical Data 10536Effective June 2021Finger-safe power distribution blocks/bussmannseriesFeatures and benefits•IP20 finger-safe under specified conditions increases safety by isolating energized connections.•Wire-ready captive termination screws cannot be misplaced and are shipped “backed out” to save time on conductor installation.• Sliding DIN-Rail latch provides easy block mounting.•For multiple pole applications, all single-pole units can be gang mounted by using the interlocking dovetail pins that are pre-installed on the side of the blocks.•Elongated panel-mounting holes provide greater flexibility and installation ease when matching up with drilled panel holes.Dual wire port application•Rated for dual wire port application to increase the possiblenumber of lineside and loadside connections. E.g., PDBFS220 can accept two wires into the lineside port (#4 - #14 Cu, #4 - #8 Al) and two wires per port (eight connections total) on the loadside lug (#8 - #14 Cu, #8 Al).•Dual wire applications are only viable when using two wires of the same size, stranding, and insulating and conductor material.Ferrule terminal application•Bussmann series PDBFS power distribution blocks are rated for use with UL Listed ferrules (see catalog number table for details).•Ferrule applications allow for the use of a broader range of conductor stranding and simulate a more efficient, solid wire connection with the PDBFS terminal port.•Always use UL Listed ferrules in accordance with the manufacturer’s specifications and instructions.Catalog numbers:(customer supplied) applied according to the manufacturer’s specifications. Ferrule ratings apply to copper wire only.** See pages 4 and 5 for the tested upstream overcurrent protective devices necessary for achieving these SCCRs.† Torque rating for dual wire and ferrule application is 30.5 N•m (270 Lb-in).†† Torque rating for ferrule application is 13.6 N•m (120 Lb-in).3Finger-safe power distribution blocksTechnical Data 10536Effective June 2021/bussmannseries Selecting SCCR power distribution blocks and terminal blocksShort-circuit current rated power distribution blocksBussmann series power distribution blocks have three distinct styles to match different application needs. There are the PDBFS_ and PDB_ high short-circuit current rated power distribution blocks and the 16_ power terminal blocks. The differences are whether the power distribution blocks are enclosed or not, and whether they are UL 1953 Listed power distribution blocks or UL 1059 Recognized power terminal blocks, which have different minimum spacing requirements. The table on this page will assist you in selecting which block is right for your application.Why these are importantPer the NEC and OSHA, equipment cannot be installed in anelectrical system at a location where the available fault (short-circuit) current is greater than the equipment’s SCCR.Further, equipment SCCRs are required in the 2014 NEC and for UL 508A Listed control panels. Marking the equipment SCCR on control panels (NEC 409.110), industrial machinery electrical panelsSelection tableThis table provides an overview of the three Bussmann series power distribution and terminal blocks mentioned above. For details on the PDB_ blocks, see data sheet number 10537. For the 16_ blocks, see data sheet numbers 10533 (UL Recognized power distribution blocks),10534 (splicer blocks) and 10535 (stud blocks).PDBFS_distribution blocksY es***Y es Y es Y es Y es Y es Y esPDB_UL 1953 Listed powerdistribution blocksNo †Y es Y es Y es Y es Y es Y es, with optional cover 16_UL 1059 Recognizedterminal blocksNo †Y esNo ††Y esNo ††Y esNo* When protected by proper fuse class with maximum ampere rating specified or smaller.** For details, see PDB and TB minimum spacing requirements for equipment table below.*** IP20 finger-safe under specific conditions, see data sheet page 5.† Optional covers are available.

The PDBFS_ and PDB_ products have the increased spacing required for use in feeder circuits of equipment listed to UL 508A (UL 1059 terminal blocks must be evaluated for proper spacings). Also, for building wiring systems, the PDBFS_ andPDB_ power distribution blocks can be used to meet the 2014 NEC requirements in section 376.56(B) for power distribution blocks in wireways.See the last page of this data sheet for SCCR tools and resources to help you further understand and solve your SCCR needs.4Technical Data 10536Effective June 2021Finger-safe power distribution blocks/bussmannseriesUpstream fusing for SCCR and minimum enclosure dataThis table contains the tested SCCR levels for each PDBFS power distribution block using the specified lineside and loadside conductors and Bussmann series Class J, RK1, RK5 and T fuses.
