Product FAQs

4 answers
Which load centers are compatible with the Eaton CL120CAF circuit breaker?

The Eaton CL120CAF is a UL Classified replacement breaker designed for use in General Electric Type THQ, Siemens Type QP, Murray Type MP, and Square D Homeline load centers. It requires one 1-inch space for installation.

Can the CL120CAF replace standard 20A breakers in compatible panels?

Yes, the CL120CAF can replace standard 1-inch, 20A single-pole breakers in approved GE, Siemens, Murray, and Square D Homeline panels when upgrading a circuit to meet current NEC requirements for combination arc fault (CAFCI) protection.

What type of arc fault protection does the CL120CAF provide?

This breaker provides Combination Arc Fault Circuit Interrupter (CAFCI) protection, which detects both series and parallel arcing faults to help prevent electrical fires. It also includes standard thermal-magnetic protection against overloads and short circuits.

Does the CL120CAF require a neutral pigtail connection?

Yes, this breaker features a pigtail neutral connection. The coiled white wire must be connected directly to the neutral bus bar in the load center to ensure the arc fault circuitry functions correctly.
