HB3B050 - 50Amp Circuit Breaker

HB3B050 - 50Amp Circuit Breaker

The Siemens HB3B050 is a 50 Amp, 3-pole BQ bolt-on circuit breaker made for your compatible Siemens electrical distribution equipment. Rated for 240V AC with a 65kA interrupting capacity, it uses a common-trip design so all three poles open together when the breaker trips. The bolt-on connection helps keep the breaker securely mounted in the panel, and load-side lugs are included for the outgoing conductors.

Where It Works Best

The Siemens HB3B050 is a practical fit for compatible Siemens BQ bolt-on panelboards and electrical distribution systems that call for a 50 Amp, 3-pole, 240V breaker with a 65kA interrupting rating. It works well for maintenance, repairs, and replacement jobs where the existing breaker type and panel arrangement need to stay the same.
