Terminal Nut Connectors

The B-frame circuit breakers may be equipped with terminal nuts and M6 power screws for direct connection to compression lugs, power distribution connectors, busbars and terminal spreaders.

These are readily field-installable, simply by removing the EverLink lug and replacing with the appropriate terminal nut assembly. They are also available factory installed (refer to Catalog Numbering.

Power Distribution Connectors

The power distribution connectors (PDCs) can be used for multiple load wire connections on one circuit breaker. Use in place of stand-alone power distribution blocks to save space and time. Field-installable kit includes tin-plated aluminum multi-conductor lug, interphase barriers, and required M6 x 24 mm mounting hardware.

The connectors are attached to circuit breaker terminals equipped with separately provided terminal nut connectors. Interphase barriers (required for installation) are supplied with power distribution connectors, but may be replaced by long terminal shields.

Power distribution connectors are available in 3 wire or 6 wire versions.

  • For use on load end of circuit breaker only.

  • For use in UL 508 Industrial Control applications.

  • For use in UL 1995/CSA C22.2 No. 236 heating and cooling equipment.

  • For copper wire only.

Spreaders

Spreaders can be used to increase the pitch of the circuit breaker from 27 mm (1.063 in.) to 35 mm (1.378 in.). They are delivered with interphase barriers and M8 screws, nuts and washers. The connectors are attached to device terminals equipped with separately provided terminal nut connectors.

Rear insulation screens may have to be used too, depending on the distance between the live uninsulated parts and the grounded metallic back pan.

Holes for customer connection use 8 mm (5/16 in.) hardware, provided.
