Product FAQs
6 answersWhat panels are compatible with the HJL432600 circuit breaker?
This breaker is designed for installation in legacy Federal Pacific distribution panels and commercial switchboards configured to accept H-frame bolt-on circuit breakers.
How does the LI trip function operate on this FPE breaker?
The LI designation indicates a thermal magnetic trip unit providing Long-Time overload protection and Instantaneous short-circuit protection. The thermal element is fixed, while the magnetic trip threshold is adjustable.
What is the required mounting method for this H-frame breaker?
The HJL432600 utilizes a bolt-on connection. It must be mechanically bolted directly to the busbars within a compatible Federal Pacific panel or switchboard.
Are there interchangeable brands for this specific HJL frame breaker?
Yes. Because the legacy Federal Pacific lines were acquired and rebranded over time, you may find exact replacements for the HJL432600 labeled under the American Circuit Breaker or Challenger brands.
Does this breaker come with load terminals?
Yes, this molded case circuit breaker is equipped with lugs for terminating the load side conductors. Ensure the wire size matches the lug capacity and is torqued to the manufacturer specifications.
What must be verified regarding the interrupting rating before installation?
Electricians must confirm that the available fault current at the panel does not exceed the 22kAIC rating at 480VAC. Installing a breaker where the fault current exceeds its interrupting capacity poses a severe safety hazard.
