B230H - 30Amp Circuit Breaker

B230H - 30Amp Circuit Breaker

The Siemens B230H BLH 30A circuit breaker is built for the kind of everyday electrical protection you want installed and working quietly in the background. Designed for 120/240V systems, this 2-pole breaker helps protect your circuits from overloads and short circuits while offering a higher 22 KAIC interrupt rating for applications where additional fault-current protection is important. It’s a solid fit for residential panels, commercial spaces, HVAC systems, and general power distribution setups.

Its thermal-magnetic trip mechanism reacts quickly when electrical issues happen, helping reduce the chance of damage to connected equipment and wiring. The bolt-on mounting style also gives installers a secure, stable connection inside compatible Siemens panelboards. With its compact design and dependable performance, the B230H is a practical choice for electricians, contractors, and maintenance teams who need reliable circuit protection without overcomplicating the job.
