B230HH – SIEMENS (HBL) 2P30A 240V BOLT ON 65kA BREAKER

The "HH" suffix denotes a High-interrupting, High-capacity rating — the B230HH carries a 65kA interrupting capacity, compared to the lower kA ratings (typically 10–22kA) found on standard B230 bolt-on breakers. This makes the B230HH the right choice when your panel's available fault current exceeds what a standard breaker can safely interrupt, as commonly required in commercial or high-service-capacity residential installations.

Siemens HBL-series bolt-on breakers can be difficult to find through general supply channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers — if the B230HH is no longer in active production, we source verified stock from our extensive inventory network. Contact us or visit one of our Calgary, Edmonton, or Vancouver counters and we'll check availability for you.

Yes. As a 2-pole 240V breaker, the B230HH is well suited for 240V loads such as electric ranges, sub-panel feeders, EV chargers, HVAC equipment, and similar circuits requiring a double-pole 30A breaker. Always verify the circuit conductor sizing (typically 10 AWG copper for 30A) and ensure your panel accepts bolt-on style breakers before installation.
