Product FAQs
5 answersCan the SEH2C100 be used to replace breakers in Eaton distribution equipment?
Yes. The SEH frame is physically and electrically compatible with Eaton F-Frame panelboards, making it a suitable replacement for aging infrastructure or for expanding existing Eaton systems.
Why might this breaker be labeled as Zinsco, Sylvania, or Challenger?
Due to historical corporate mergers, the SEH frame was produced under the Zinsco, GTE Sylvania, and Challenger brand names. Breakers carrying any of these names are interchangeable as long as the frame type, amperage, and voltage ratings match.
How is the SEH2C100 wired and mounted during installation?
The line side of the breaker bolts directly to the bus bars of a compatible panelboard. The load side features mechanical lugs that accept 14 AWG to 1/0 AWG aluminum or copper conductors.
Are the thermal and magnetic trip thresholds adjustable on this model?
No. The SEH2C100 features a fixed thermal-magnetic trip unit. The long-time thermal protection and instantaneous magnetic protection are factory set and cannot be field calibrated.
Will this breaker fit standard residential load centers?
No. The SEH2C100 is a commercial molded case circuit breaker designed specifically for bolt-on panelboards like the Eaton F-Frame, Sylvania, Challenger, and Westinghouse series. It is not compatible with standard residential plug-on load centers.
