Product FAQs
7 answersCan I use the FDC3020L to replace an older FD3020L or HFD3020L breaker?
Yes. The FDC3020L shares the exact same physical dimensions as the standard FD and high-interrupting HFD frames. It features an ultra-high interrupting capacity of 100kA at 480VAC, making it a safe, direct drop-in upgrade for applications requiring superior fault protection.
Is the Eaton FDC3020L interchangeable with older Westinghouse versions?
Yes. Eaton acquired the Westinghouse distribution equipment line and integrated it under the Cutler-Hammer and Eaton brands. An FDC3020L labeled as Westinghouse, Cutler-Hammer, or Eaton will have identical physical dimensions and electrical characteristics.
What does the L suffix indicate on the FDC3020L catalog number?
The L suffix designates that the circuit breaker is supplied with standard factory-installed pressure terminals (lugs) on both the line and load sides. Without this suffix, the breaker would be shipped without lugs.
Can the trip unit on the FDC3020L be adjusted or swapped in the field?
No. This specific breaker features a fixed thermal and fixed magnetic trip unit. The trip mechanism is non-interchangeable and cannot be modified, adjusted, or replaced in the field.
What type of equipment is the FDC3020L designed to be installed in?
This unit-mount F-frame breaker is designed for use in Eaton Series C panelboards, motor control centers (MCCs), and industrial switchboards. It mounts directly to the chassis or mounting pan using standard hardware.
Are the included lugs rated for both copper and aluminum conductors?
Yes. The standard pressure terminals provided with this breaker are dual-rated for both copper (Cu) and aluminum (Al) conductors, safely accommodating wire sizes from 14 AWG up to 1/0 AWG.
Is the FDC3020L suitable for direct current (DC) applications?
Yes. In addition to its alternating current ratings, this thermal-magnetic breaker is rated for up to 250VDC with a 22kA interrupting capacity. It can be utilized in DC control panels, battery systems, and other industrial DC applications.
