B2100– SIEMENS (BL) 2P 100A 240V BOLT ON 10kA BREAKER

No — the BL series uses a bolt-on mounting method where the breaker is physically bolted to the bus bar, while QP breakers clip in via a plug-in connection. These two mounting styles are not interchangeable. If your Siemens/ITE loadcentre uses plug-in breakers, you would need a QP-frame 2-pole 100A breaker instead. Check your panel's interior label or send us the model number and we'll point you to the right breaker.

Yes — a 2-pole 100A bolt-on breaker like the B2100 is commonly used as a sub-panel feed or main disconnect breaker in applications where the panelboard supports a bolt-on main. However, suitability as a 'main' breaker depends on your specific panel's design and whether it is listed for use in that position. Always verify with the panel manufacturer's documentation or a licensed electrician, and ensure the installation meets local Canadian Electrical Code (CEC) requirements.
