HB3B030 - 30Amp Circuit Breaker

HB3B030 - 30Amp Circuit Breaker

Finding the right replacement breaker is all about matching the original specifications, and the Siemens HB3B030 is built for exactly that purpose. This 30 Amp, 3-pole BQ bolt-on circuit breaker is designed for use in compatible Siemens electrical distribution equipment and is rated for 240V AC with a 65kA interrupting capacity (AIC). Its common-trip design disconnects all three poles at the same time if an overload or short circuit occurs, helping protect connected equipment and branch circuits. If you're maintaining an existing electrical system or replacing a breaker with matching specifications, the HB3B030 delivers the same form, fit, and intended function.
