B31500S01 - 15 Amp Circuit Breaker

B31500S01 - 15 Amp Circuit Breaker

The Siemens B31500S01 circuit breaker is built for your three-phase electrical systems that need reliable circuit protection and remote trip capability. Rated at 15 amps for 120/240V applications, this 3-pole Type BL breaker helps protect your wiring and connected equipment from overloads and short circuits in commercial and industrial electrical systems. This model includes a factory-installed 120V shunt trip, allowing the breaker to be remotely opened through an external signal. That makes it a good fit for emergency shutoff systems, fire alarm interfaces, HVAC controls, and other applications where remote disconnect capability is required. The bolt-on construction provides a secure fit in compatible Siemens panelboards and distribution equipment, making it a practical option for replacements, upgrades, and new installations.
