B32000S01 - 20Amp Circuit Breaker

B32000S01 - 20Amp Circuit Breaker

The Siemens B32000S01 circuit breaker is a practical solution for your three-phase electrical systems that need both dependable circuit protection and remote trip capability. Rated at 20 amps for 120/240V applications, this 3-pole Type BL breaker includes a factory-installed 120V shunt trip, allowing the breaker to be opened remotely through external control or emergency shutdown systems. In many commercial and industrial setups, having the ability to remotely disconnect power can make troubleshooting, safety shutdowns, and equipment protection much easier. That’s where the B32000S01 fits in. It helps protect your circuits, wiring, and connected equipment from overloads and short circuits while also supporting applications that require remote breaker operation. The thermal magnetic trip mechanism responds to both long-term overloads and sudden fault conditions, helping reduce the risk of damage to electrical systems during everyday operation. Its bolt-on mounting style provides a secure fit in compatible Siemens panelboards and distribution equipment, while the compact design helps save valuable panel space. The Siemens B32000S01 is commonly used in HVAC systems, industrial machinery, control panels, OEM equipment, and emergency shutdown systems where standard circuit protection alone may not be enough.
