Product FAQs
6 answersWhat equipment is compatible with the FL360100A circuit breaker?
This F-frame breaker is specifically designed to fit legacy Westinghouse panelboards and FDP fusible switches. Using this exact model allows you to maintain older commercial electrical systems without needing modern retrofit kits.
How does the FL360100A mount into a panelboard?
It features a unit mount configuration, commonly known as a bolt-on design. The breaker must be physically bolted to the bus or mounting pan, which provides a highly secure connection compared to plug-on alternatives.
Is the FL360100A rated for use in DC electrical systems?
Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with a 10kA interrupting capacity. This allows it to be safely deployed in compatible direct current applications.
Can I adjust the trip curve settings on the FL360100A?
No, this breaker is equipped with fixed thermal and fixed magnetic trip units. It provides standard protection, but the trip thresholds cannot be manually adjusted in the field.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the breaker provides Long-Time and Instantaneous trip functions. The long-time function protects against sustained overloads, while the instantaneous function trips the breaker immediately during a severe short circuit.
Is the FL360100A a modern or legacy circuit breaker?
The FL360100A belongs to the legacy Westinghouse F-frame family, which is now supported by Eaton and Cutler-Hammer. It is primarily sourced to service and maintain existing older panelboards where preserving the original equipment layout is required.
