EHC3030 - 30Amp Circuit Breaker

EHC3030 - 30Amp Circuit Breaker

When you need to replace an existing Type EHC circuit breaker, having the correct ratings and physical fit matters. The EHC3030 is a 3-pole, 30 amp thermal-magnetic circuit breaker designed to provide the proper form, fit, and function for compatible electrical distribution equipment. Whether you're performing scheduled maintenance, replacing a failed breaker, or keeping a legacy system operating as intended, this breaker is built to match the original equipment's specifications.

Its thermal-magnetic trip mechanism responds to both sustained overloads and short-circuit conditions, helping protect connected equipment and electrical circuits. The non-interchangeable trip unit preserves the original breaker configuration, while the included load terminals help simplify installation in compatible systems.
