HMA3700 - 700Amp Circuit Breaker Description

HMA3700 - 700Amp Circuit Breaker

The HMA3700 is a 700-amp, 3-pole thermal-magnetic circuit breaker designed for equipment that uses the HMA breaker configuration. When you're replacing a breaker in an existing electrical system, the details matter—matching the amp rating, pole count, trip unit, dimensions, and electrical ratings helps ensure the replacement is the correct fit. For facilities and technicians working with established distribution systems, confirming the breaker specifications before replacement can help avoid compatibility issues. When properly matched to the application, the HMA3700 provides the expected fit and function of a compatible HMA breaker and is built to last.
