B220– SIEMENS (BL) 2P 20A 240V BOLT ON 10kA BREAKER

The BL series uses a bolt-on mounting method, where the breaker is physically bolted to the bus bar, whereas QP/QT breakers clip in using a plug-in design. These two types are not interchangeable. If your Siemens panel has a bolt-on bus (common in older ITE/Siemens EQ or ES panelboards), the B220 is the correct style. Check your panel's label or send us your panel model and we'll verify compatibility before you order.

The BL series is considered a legacy/obsolete Siemens line and may no longer be in active production. Northern Breaker Group specializes in hard-to-find and obsolete breakers, so we maintain stock of BL-series units like the B220. Contact us for current availability — our Calgary, Edmonton, and Vancouver counters can also provide same-day assistance on urgent requests.

A 2-pole 20 A 240 V breaker like the B220 is commonly used for circuits such as electric baseboard heaters, small air conditioning units, well pumps, or other dedicated 240 V appliances drawing up to 20 A. Always verify that the load's amperage and voltage requirements match the breaker's 20 A / 240 V rating and that the circuit wiring is sized appropriately (typically 12 AWG minimum for a 20 A circuit per Canadian Electrical Code).
