Which panelboards accept the Federal Pacific HJL634150 circuit breaker?

Yes, it serves as a true H-frame replacement for aging FPE infrastructure. It fits seamlessly into classic Federal Pacific enclosures without the need to source modern retrofit adapters.

Can the HJL634150 share mounting hardware with NJL frame breakers?

Yes, in certain Federal Pacific panelboards like the CDP and BDP series, the HJL and NJL frame breakers utilize the same twin-mount hardware kits. Always verify your specific panel configuration before installation.

What safety standards apply to the FPE HJL634150?

This molded case circuit breaker is built to UL 489 standards for use in commercial and industrial power distribution systems. It also carries a standard 40C ambient temperature rating.

    Great Customer Service

    Working with Superbreakers the team is so helpful. They answer the phone and are very accommodating. We had an issue with the refurbished breaker not working out and they helped get a new one out right away.
