Description
Built for commercial and industrial applications, this 60A three-phase component mounts into classic FPE panelboards. It provides a reliable solution for aging infrastructure, serving as an exact cross-reference for the obsolete NEF631060 while maintaining the original bolt-on footprint. Rated for 42kAIC at 240VAC, the thermal-magnetic trip mechanism ensures robust overcurrent protection without requiring aftermarket adapters or modifications.Specifications

Product FAQs
6 answersWhat panelboards accept the HEF631060 circuit breaker?
This breaker is designed for installation in legacy Federal Pacific (FPE) commercial panelboards and switchboards configured for H-frame bolt-on breakers.
Is the HEF631060 part of the recalled FPE Stab-Lok series?
No. The HEF631060 is a commercial-grade molded case circuit breaker (MCCB) with a bolt-on connection. It is not part of the residential Stab-Lok series, which has documented safety controversies.
Are the trip settings on the HEF631060 adjustable?
No, this breaker features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions. The trip curve settings cannot be adjusted in the field.
Can the HEF631060 be used in direct current (DC) systems?
Yes, this breaker is rated for use in DC systems up to 250VDC, providing an interrupting capacity of 10kA at that voltage.
Does this breaker support aluminum conductors?
Yes, the factory-installed mechanical lugs are dual-rated for both copper and aluminum conductors, accepting wire sizes from 4 AWG up to 1/0 AWG. Ensure proper application of oxide-inhibiting joint compound when terminating aluminum wire.
Is the Federal Pacific HEF631060 still actively manufactured?
Federal Pacific Electric (FPE) is no longer in business, so original OEM production of this breaker has ceased. Exact replacements are sourced from existing legacy inventory.
