Built for legacy commercial facilities, the HEF631030 is a 3-pole, 30A molded case circuit breaker by Federal Pacific. It provides essential thermal-magnetic protection for industrial applications. This unit installs into existing FPE panelboards and switchboards, serving as a seamless bolt-on replacement for the NEF631030. It eliminates the need for aftermarket adapters. Performance features include a 22kAIC rating at 480VAC, fixed trip adjustability, and included load side lugs.
This bolt-on molded case circuit breaker is designed specifically for legacy Federal Pacific panelboards and switchboards that accept H-frame breakers. It is not compatible with residential Stab-Lok load centers.
Can the HEF631030 replace older NEF series breakers?
Yes, this unit serves as a direct, seamless bolt-on replacement for the discontinued NEF631030. It installs into the same FPE enclosures without requiring aftermarket adapters or hardware modifications.
What applications is the 250VDC rating suitable for?
With a 10kA interrupting capacity at 250VDC, this breaker can be utilized in industrial DC control circuits, legacy DC motor drives, and ungrounded battery systems requiring a 30-amp thermal-magnetic trip.
What wire types are supported by the included load-side lugs?
The factory lugs accept 14 AWG to 2 AWG wire and are rated for both copper and aluminum conductors. This provides flexibility when terminating field wiring in older commercial facilities.
Is the HEF631030 part of the FPE Stab-Lok residential line?
No. The HEF series is a commercial and industrial-grade molded case circuit breaker with a bolt-on connection. It does not use the Stab-Lok plug-on design associated with older residential Federal Pacific panels.
