B220HH – SIEMENS (HBL) 2P20A 240V BOLT ON 65kA BREAKER

Bolt-on breakers like the B220HH physically bolt to the bus bar rather than snapping on, providing a more secure mechanical and electrical connection. This is typically required in commercial panelboards or in panels specifically rated for bolt-on devices. Plug-on and bolt-on breakers are not interchangeable, so it's important to confirm your panel type before ordering.

The 65kA interrupting capacity means the breaker can safely clear fault currents up to 65,000 amperes — a high rating suited for commercial installations or locations close to the utility transformer where available fault current is elevated. For residential applications the required interrupting rating is often lower, but using a higher-rated breaker is always acceptable and adds a safety margin. Your electrical engineer or authority having jurisdiction (AHJ) can confirm the required rating for your specific installation.

Availability of specific HBL series breakers can vary. Northern Breaker Group specialises in obsolete, discontinued, and hard-to-find breakers across Canada, with counter locations in Calgary, Edmonton, and Vancouver.
