Product FAQs

4 answers
Which panelboards are compatible with the SEH3C015 circuit breaker?

This bolt-on breaker is designed for use in legacy Sylvania, Challenger, and Westinghouse panelboards, as well as Eaton F-Frame panelboards.

Can the Sylvania SEH3C015 replace other legacy breakers?

Yes. Because Sylvania's commercial molded case lines were later acquired and rebranded, this breaker is often used to replace equivalent Challenger or Westinghouse F-Frame breakers with matching specifications.

What wire sizes are accepted by the terminals on the SEH3C015?

The standard lugs accommodate 14 AWG through 1/0 AWG aluminum or copper conductors. Always verify the specific torque requirements labeled on the breaker face or panelboard before terminating.

Are there special installation requirements for mounting this breaker in older panels?

As a bolt-on molded case circuit breaker, it mounts directly to the busbar. When installing in legacy Sylvania or Challenger panels, inspect the busbar connections to ensure they are clean and free of pitting or thermal damage before securing the breaker.
