Product FAQs

7 answers
What is the modern replacement for the Challenger C2100 circuit breaker?

The Eaton BR2100 is the direct, UL listed modern replacement for the Challenger C2100. Eaton acquired the Challenger line, and their Type BR breakers are fully compatible with legacy Challenger Type C load centers.

Which load centers are compatible with the C2100 breaker?

This plug-on breaker is designed for use in Challenger Type C load centers. It is also fully compatible with Eaton Type BR and Westinghouse Type BR load centers.

How many panel spaces does the C2100 require?

This two-pole miniature circuit breaker requires two standard 1-inch spaces on the panel bus.

Can I use the C2100 as a main breaker?

While typically used as a branch or feeder breaker, the C2100 can function as a back-fed main breaker in compatible panels if secured with an approved hold-down kit.

What are the terminal torque specifications for the C2100?

For the box lug terminals, torque 4 AWG wire to 27 in-lbs, and 3 AWG through 1/0 AWG wire to 45 in-lbs. Always verify the label on the breaker before finalizing connections.

Is this breaker suitable for use with aluminum wiring?

Yes, the box lugs on the C2100 are rated for both copper and aluminum (Cu/Al) conductors ranging from 4 AWG to 1/0 AWG.

What does the LI trip function code indicate on the C2100?

The LI designation means the breaker includes Long-Time and Instantaneous trip functions. The long-time thermal element protects against gradual overloads, while the instantaneous magnetic element trips immediately during short circuits.
