A drop-in replacement for older Federal Pacific (FPE) panelboards, the HEJ233225 is a 3-pole, 225A molded case circuit breaker. It provides thermal-magnetic protection for commercial systems at 240VAC. Designed to fit existing infrastructure, this bolt-on MCCB replaces the obsolete NEJ233225 and crosses to UBIHEJ233225, ensuring a seamless fit without panel modifications. Featuring a 42 kAIC rating at 240V, it handles demanding fault currents with fixed LI trip functions.

This breaker is designed for use in legacy Federal Pacific Electric (FPE) commercial panelboards, such as CDP series panels, that accept H-frame bolt-on breakers.
What obsolete Federal Pacific breakers can the HEJ233225 replace?
The HEJ233225 serves as a direct drop-in replacement for the obsolete NEJ233225 circuit breaker. It fits into the same enclosures without requiring panel modifications.
Are there aftermarket alternatives to the Federal Pacific HEJ233225?
Yes, this breaker crosses over to the UBIHEJ233225, which is an aftermarket replacement manufactured by Connecticut Electric for legacy FPE systems.
Does this breaker require specific mounting hardware for installation?
Yes, installing this breaker in an FPE CDP panelboard typically requires a twin mounting hardware strap kit, such as the KCDP-2C, to properly secure the H-frame breaker to the busbars.
Is the HEJ233225 affected by the residential Stab-Lok safety issues?
No. The HEJ233225 is a commercial-grade, bolt-on molded case circuit breaker. It does not use the Stab-Lok plug-on design associated with legacy FPE residential load centers.
