B370HH00S01 - 70Amp Circuit Breaker

B370HH00S01 - 70Amp Circuit Breaker

The Siemens B370HH00S01 circuit breaker is built for commercial and industrial electrical systems that need dependable protection and remote trip capability. Rated at 70 amps with a 120/240VAC rating, this 3-pole molded case circuit breaker helps protect your equipment and power distribution systems from overloads and short circuits before they become larger problems.

A factory-installed 120V shunt trip allows the breaker to trip remotely through connected safety or emergency shutdown systems, making it a practical option for facilities where quick disconnect capability is important. The thermal magnetic trip mechanism responds to both overloads and fault currents to help maintain safe and reliable operation.
