Product FAQs
8 answers
What equipment is the FDC3200LH12 designed to fit?
This Series C F-frame breaker is engineered for use in Eaton and Cutler-Hammer switchboards, motor control centers (MCCs), and industrial control panels that accept unit-mount, bolt-on breakers.
What does the C in the FDC3200LH12 part number indicate?
The C designates this as the high-interrupting capacity version of the F-frame series. It provides 100 kAIC at 480V, which is significantly higher than standard FD breakers, making it suitable for systems with high available fault currents.
Are lugs included with the FDC3200LH12, and what wire sizes do they accept?
Yes, this breaker comes with factory-installed lugs that accommodate wire gauges from 4 AWG to 4/0 AWG. Ensure your conductors are sized appropriately for the 200A rating according to the National Electrical Code.
Is the trip unit on this breaker adjustable?
No, the FDC3200LH12 features a fixed thermal and fixed magnetic trip unit. The long-time (thermal) and instantaneous (magnetic) trip functions are factory-set for 200 amps and cannot be field-adjusted.
Can I use this to replace an older Cutler-Hammer FDC3200 breaker?
Yes. Eaton manufactures the Series C line, which is fully backwards compatible with legacy Cutler-Hammer and Westinghouse Series C F-frame breakers sharing the same base catalog number.
Does this breaker plug onto a busbar?
No, the FDC3200LH12 is a unit-mount, bolt-on breaker. It must be physically bolted to the mounting pan or chassis and hardwired, rather than plugging directly onto a panelboard bus.
Can this breaker be used in DC circuits?
Yes, the FDC3200LH12 is rated for 250VDC applications with an interrupting capacity of 22 kAIC, making it suitable for specific industrial DC control and distribution systems.
Does the FDC3200LH12 provide ground fault protection?
No, this is a standard thermal-magnetic breaker designed for overcurrent and short-circuit protection. It does not include integrated ground fault circuit interruption or equipment ground fault protection.
