B3100H - 100Amp Circuit Breaker

B3100H - 100Amp Circuit Breaker

The Siemens B3100H circuit breaker is built for your three-phase electrical systems that need dependable 100 amp protection and a higher interrupting rating than standard breakers. Designed for 240V applications, this 3-pole Type BLH breaker helps protect your circuits and equipment from overloads and short circuits in commercial and industrial power distribution systems.

Its 22kA interrupting capacity makes it a good fit for systems where available fault current is higher and added protection is needed. The thermal magnetic trip design responds to both overloads and fault conditions, helping protect electrical equipment during normal operation.

The bolt-on design provides a secure connection in compatible Siemens panelboards and distribution equipment, making installation and replacement work more straightforward. Its compact size also works well in panelboards and control equipment where space may be limited. The Siemens B3100H is commonly used in feeder circuits, control panels, OEM equipment, and general electrical distribution systems where reliable three-phase protection is required.
