Description

A drop-in replacement for older installations, the Eaton FCL3050 is a 3-pole, 50A molded case circuit breaker from the legacy Westinghouse F-Frame family. This unit-mount breaker integrates into Eaton Series C panelboards, switchboards, and MCCs, ensuring exact compatibility for legacy system upgrades. Rated at 150 kAIC at 480VAC, the current-limiting design minimizes let-through energy during electrical faults to safeguard downstream components.

Product FAQs

7 answers
What enclosures or panelboards accept the FCL3050?

This unit mount F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It serves as an exact physical replacement for legacy Westinghouse equipment.

What does the current limiting designation mean for the FCL3050?

As a current limiting breaker, it clears electrical faults extremely fast to minimize let-through energy. This protects downstream components from severe thermal and magnetic stress during a short circuit, achieving a 150kAIC rating at 480VAC without requiring external fuses.

Is the Westinghouse FCL3050 the same as the Eaton FCL3050?

Yes. Eaton acquired the Westinghouse distribution equipment division. The FCL3050 is manufactured to the exact same physical and electrical specifications, making it a direct drop-in replacement for legacy Westinghouse or Cutler-Hammer installations.

Can the FCL3050 be reverse fed?

Yes. Standard thermal magnetic FCL breakers do not have line and load markings, meaning they are suitable for reverse feed applications. Always ensure you use the appropriate retaining bracket or hold-down kit when backfeeding the breaker in a panel.

Are the trip settings adjustable on the FCL3050?

No. This breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous protection but does not have adjustable dials to modify the trip curve.

What wire sizes are accepted by the standard lugs on the FCL3050?

The factory lugs on this breaker accept 14 AWG to 1/0 AWG conductors. If your installation requires larger wire, alternate lug kits must be sourced separately.

Does the FCL3050 require external fuses to achieve its 150kAIC rating at 480V?

No. The FCL3050 is a standalone current limiting molded case circuit breaker. Its internal design allows it to safely interrupt up to 150,000 amps at 480VAC without the need for backup fuses.
