Product FAQs

6 answers
What equipment is the FD2100L circuit breaker compatible with?

The FD2100L is an F-frame unit mount breaker designed for use in Eaton Series C panelboards, FDPW panelboards, switchboards, and motor control centers. It is not interchangeable with bolt-on or plug-on breakers.

What does the "L" suffix in the FD2100L catalog number indicate?

The "L" suffix indicates that the circuit breaker is supplied with factory-installed line and load terminals (lugs). Catalog numbers without this suffix, such as the base FD2100, may be supplied with load-side terminals only or without lugs entirely.

What wire sizes are accepted by the standard lugs on the FD2100L?

The factory-installed lugs on the FD2100L accept 14 AWG to 1/0 AWG copper or aluminum (Cu/Al) conductors. Always verify proper torque specifications on the breaker faceplate prior to terminating the wires.

How is the FD2100L mounted in an electrical system?

The FD2100L is a unit mount, feed-thru circuit breaker. Instead of connecting directly to a panelboard bus bar, it is individually mounted and wired using the provided line and load lugs.

Can the FD2100L be used in DC applications?

Yes, because it utilizes a thermal-magnetic trip unit, the FD2100L is suitable for DC applications up to 250VDC. It provides a 10kAIC interrupting capacity for DC circuits.

Are the trip settings on the FD2100L adjustable?

No, the FD2100L features a fixed thermal and fixed magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip functions are factory set and cannot be adjusted in the field.

    175amp molded case circuit breaker

    The breaker we purchased was as advertised. The breaker fit perfectly. We purchased reconditioned breaker and it seems to be working properly, accordingly to the golf course maintenance team that supervises the irrigation system.

    Next day shipping came quickly even though the 4th of July was coming.

    I wish it came with new installations hardware but that isn’t a deal breaker.
