B115H – SIEMENS 1P15A 120V BOLT ON 22kA BREAKER

The B115H uses a bolt-on connection, where the breaker is mechanically fastened to the bus bar with a screw for a more secure, vibration-resistant connection. Plug-in breakers like the QP115 simply clip onto the bus. The two styles are not interchangeable — your panel must specifically accept bolt-on breakers. If you're unsure which type your panel requires, send us your panel model and we'll help you confirm.

Yes. The B115H's 22kA interrupting rating makes it appropriate for both residential and light commercial applications where fault current levels are within that threshold. It must be installed in a compatible bolt-on panelboard and in compliance with the Canadian Electrical Code (CEC). Always verify your panel's available fault current (AFC) matches or is below the breaker's 22kA rating.

Availability can vary as product lines evolve. Northern Breaker Group specializes in hard-to-find and obsolete breakers across Canada, so even if the B115H is discontinued or difficult to source through regular channels, we may have stock or a verified equivalent.
