Product FAQs
6 answersWhich panelboards accept the HEJ233150 circuit breaker?
This breaker is engineered specifically for legacy Federal Pacific (FPE) panelboards that accommodate H-Frame bolt-on breakers. It is used to maintain older electrical infrastructure without requiring a complete panel overhaul.
What are the wire gauge requirements for the HEJ233150?
The included load-side lugs accept wire sizes from 4 AWG up to 300 kcmil. Electricians must size the conductors appropriately for a 150A load and ensure proper torque is applied during installation.
How does the LI trip function operate on this FPE breaker?
The thermal-magnetic trip unit provides Long-Time (L) protection for sustained overloads and Instantaneous (I) protection for immediate short-circuit clearing. Both the thermal and magnetic trip points are fixed and cannot be adjusted in the field.
What is the interrupting capacity of the HEJ233150?
The breaker delivers a standard interrupting rating of 22kAIC at 240VAC, and carries a maximum rating of up to 42kAIC at 240VAC depending on the specific system configuration. This capacity makes it suitable for demanding commercial applications.
Is the Federal Pacific HEJ233150 still manufactured?
Federal Pacific Electric (FPE) is no longer in business, and original HEJ frame breakers are out of production. This model is sourced to support and maintain existing legacy FPE systems that require exact bolt-on replacements.
Are there any specific safety considerations when replacing an FPE HEJ breaker?
When servicing legacy Federal Pacific equipment, always verify that the panel busbars are in good condition and free of pitting or thermal damage before bolting on the replacement breaker. Ensure the system is fully de-energized prior to installation.
