B250– SIEMENS (BL) 2P 50A 240V BOLT ON 10kA BREAKER

No, they are not interchangeable. The BL series uses a bolt-on mounting method where the breaker is mechanically fastened to the bus bar, while QP breakers use a plug-in clip design. Each type requires a compatible panel bus — installing the wrong style can result in a loose, unsafe connection. Check your panel's bus type before ordering, or contact us and we'll help you identify the correct breaker.

Yes. The B250 is a 2-pole, 240V, 50A breaker, making it well suited for double-pole 240V loads such as electric ranges, dryers, EV chargers, hot tubs, or a 50A subpanel feeder. Its 10kA interrupting capacity meets typical residential and light commercial fault-current requirements in Canada.

The Siemens BL bolt-on series has seen limited availability through standard distribution channels, and certain variants may be considered hard-to-find.
