Product FAQs
7 answersWhich panelboards are compatible with the SF2C225 circuit breaker?
This breaker is designed for use in legacy Challenger, Sylvania, and Zinsco panelboards that accept SF frame molded case circuit breakers.
Why is this breaker listed under Challenger, Sylvania, and Zinsco brands?
Through historical acquisitions, the SF frame design was manufactured under the Challenger, Sylvania, and Zinsco brand names. Breakers from these brands with the SF2C225 catalog number share the same physical dimensions and electrical characteristics.
What is the Eaton equivalent for the SF2C225 circuit breaker?
Eaton acquired the Challenger line and manufactures F-frame replacements for legacy SF breakers. The Eaton FD2225 is a common Series C cross-reference for this 225A, 2-pole, 480V configuration.
How does the SF2C225 mount into the panelboard?
This is a bolt-on molded case circuit breaker. It secures directly to the panelboard bus using bolted connections rather than a plug-on mechanism.
Are the trip settings adjustable on the SF2C225?
No, this breaker features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings for both long-time and instantaneous protection.
Can I use this breaker in a 240V system?
Yes, while it is rated for a maximum of 480VAC, it is fully compatible with 240VAC systems and provides a higher interrupting capacity of 65kA at the lower voltage.
What type of terminals are included on the SF2C225?
This breaker comes equipped with standard lug terminals for wire connections.
