Product FAQs
7 answersWhat types of equipment are compatible with the FDC3040 breaker?
This F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It utilizes a bolt-on connection for secure unit mounting within these enclosures.
What wire sizes do the standard lugs on this 40A breaker accept?
The standard lugs accommodate wire gauges from 14 AWG up to 1/0 AWG. Ensure you use properly rated conductors and torque the terminals to the manufacturer specifications during installation.
What does the C in the FDC prefix indicate compared to standard FD breakers?
The C indicates an ultra-high interrupting capacity. While standard Series C FD breakers are rated for 35kAIC at 480VAC, the FDC series provides a much higher 100kAIC rating at 480VAC for systems requiring maximum fault protection.
Can this Eaton breaker replace older Cutler-Hammer FDC3040 models?
Yes. Eaton acquired the Cutler-Hammer circuit breaker division. An Eaton FDC3040 is the direct replacement for older Cutler-Hammer breakers bearing the exact same FDC3040 catalog number.
Is the trip unit on the FDC3040 adjustable?
No. This breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous protection, but the trip thresholds cannot be adjusted in the field.
Can the FDC3040 be used in DC applications?
Yes, this breaker is rated for up to 250VDC with an interrupting capacity of 22kAIC. It is suitable for both AC and DC systems within its specified voltage limits.
What safety precautions should be taken before installing the FDC3040?
Always de-energize the panelboard or switchboard before installation. Verify that the system voltage and available fault current do not exceed the 600VAC and 100kAIC at 480VAC maximum ratings of this breaker.
