B3100HH - 100Amp Circuit Breaker

B3100HH - 100Amp Circuit Breaker

The Siemens B3100HH circuit breaker is designed for your three-phase electrical systems that require dependable protection in applications with higher available fault current. Rated at 100 amps and built for 240V systems, this 3-pole Type HBL breaker helps protect your circuits and connected equipment from overloads and short circuits in commercial and industrial power distribution systems. Its 65kA interrupting capacity makes it a strong choice for demanding electrical applications where standard breakers may not provide enough fault protection. The bolt-on construction provides a secure fit in compatible Siemens panelboards and distribution equipment, making installation and replacement work more straightforward. Its compact design also helps in panelboards and control equipment where available space may already be limited.
