B39000S01 - 90Amp Circuit Breaker

B39000S01 - 90Amp Circuit Breaker

The Siemens B39000S01 circuit breaker is designed for commercial and industrial electrical systems that need dependable circuit protection with remote trip capability. Rated at 90 amps and built for 120/240VAC applications, this 3-pole molded case circuit breaker helps protect your electrical distribution systems from overloads and short circuits that can damage equipment or interrupt operation. This breaker includes a factory-installed 120V shunt trip, allowing the breaker to be remotely tripped through an external control signal. That makes it a practical option for emergency shutdown systems, safety controls, and automated equipment applications where remote disconnect capability is important. Part of the Siemens Type BL series, the B39000S01 uses a thermal magnetic trip mechanism that responds to both overload conditions and fault currents. The bolt-on mounting design provides a secure connection in compatible panelboards and switchboards, while the compact construction helps simplify installation and replacement work.
