Product FAQs
7 answersDoes the HNC31200F breaker come with a rating plug installed?
No, this item is sold as a frame only. The continuous current rating is determined by the separate rating plug you install, which can be sized lower than the 1200A maximum frame capacity to match your circuit conductors.
Is the HNC31200F part of the Seltronic or Series C product line?
It originated in the Westinghouse Seltronic family but is fully integrated into the Eaton Series C N-Frame group. It is mechanically and electrically compatible with Series C N-Frame hardware.
What panels or switchboards are compatible with this breaker frame?
The HNC31200F is designed for direct bolt-on installation in Eaton Series C panelboards and switchboards.
Can the HNC31200F be used in place of the newer HND31200 breaker?
Yes, the HNC31200F shares the same physical footprint and serves as an exact cross-reference for the newer HND31200. Always verify that its 50kA at 480V interrupting capacity meets your specific system fault requirements.
Why is this breaker associated with Westinghouse, Cutler-Hammer, and Eaton?
Eaton acquired the Westinghouse electrical distribution division and later branded these lines under Cutler-Hammer and Eaton. A breaker with this exact catalog number may display any of these brand names depending on its manufacturing date, but they are physically identical.
What protection adjustments are available on the electronic trip unit?
The solid state electronic trip unit features an LS function code, providing adjustable long-time and short-time overcurrent protection settings. This allows for precise coordination with other protective devices in your electrical system.
Does this circuit breaker provide ground fault protection?
No. The LS trip unit provides long-time and short-time protection only. It does not include an integral ground fault (G) monitoring function.
