Product FAQs
6 answersWhat is the modern replacement for the legacy FCP34080MT circuit breaker?
The FCP34080MT is a legacy F-Frame unit. For facilities updating their infrastructure, Square D replaces this model with the PowerPact H-Frame series, specifically catalog number HJL36080.
Which electrical distribution systems can accommodate the FCP34080MT?
This bolt-on breaker is engineered specifically for legacy Square D panelboards, switchboards, and motor control centers designed to accept F-Frame molded case circuit breakers.
What are the wiring requirements for the FCP34080MT terminals?
The breaker comes equipped with line and load side lugs that accept either copper or aluminum conductors. The supported wire range is 14 AWG to 1/0 AWG.
What does the 'C' in the FCP34080MT catalog number indicate?
In Square D's legacy naming convention, the 'C' designates an extra-high interrupting capacity. This allows the breaker to safely clear faults up to 100kA at 240VAC and 65kA at 480VAC.
Can the FCP34080MT be used to protect HVAC equipment?
Yes, this breaker is HACR rated, certifying it for safe use with heating, air conditioning, and refrigeration systems that require specialized short-circuit and overload protection.
Are the trip settings on the FCP34080MT adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip functions are factory-set and non-interchangeable.
