Description

Built for demanding industrial environments, the Eaton FCL3040 is a 3-pole, 40A molded case circuit breaker from the legacy F-Frame series. Designed for unit mounting, it fits seamlessly into Eaton Series C panelboards and motor control centers as a direct replacement for older systems. With a robust 150 kAIC rating at 480VAC, its current-limiting capability restricts fault currents to protect sensitive downstream equipment.

Product FAQs

5 answers
What equipment is compatible with the FCL3040 circuit breaker?

This F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It features a bolt-on connection for unit mounting.

What wire gauge range do the standard lugs on the FCL3040 accept?

The standard lugs accommodate wire sizes from 14 AWG up to 1/0 AWG. Ensure proper torque specifications are followed during installation as outlined by the manufacturer.

How does the current limiting feature of the FCL3040 operate?

As a current limiting breaker, it is designed to clear a fault in less than half a cycle. This rapid operation significantly reduces the let-through energy and peak let-through current during a short circuit, protecting downstream equipment.

Can the Eaton FCL3040 replace older Westinghouse FCL3040 breakers?

Yes. Eaton acquired the Westinghouse distribution equipment line. The current Eaton FCL3040 is a direct drop-in replacement for legacy Westinghouse or Cutler-Hammer breakers with the exact same catalog number.

Are the thermal or magnetic trip settings adjustable on this breaker?

No. The FCL3040 features a non-interchangeable thermal magnetic trip unit with fixed long-time and fixed instantaneous trip functions. Neither the thermal nor the magnetic elements can be adjusted in the field.
