B330HH - 30Amp Circuit Breaker

B330HH - 30Amp Circuit Breaker

The Siemens B330HH circuit breaker is a dependable option for your three-phase electrical systems that need stronger fault protection without taking up unnecessary space in the panel. Rated at 30 amps and built for 240V applications, this Type HBL breaker helps protect your wiring, panels, and connected equipment from overloads and short circuits in commercial and industrial environments. One thing that stands out about the B330HH is its high 65kA interrupting rating. That added protection makes it a smart fit for systems where available fault current levels are higher and reliable performance matters day after day. The thermal magnetic trip design reacts to both overload conditions and sudden fault events, helping reduce the risk of downtime or equipment damage.
