Panel Compatibility

The Siemens BQ3B035 is a bolt-on breaker from the BQ (BL/BA) frame series, designed to install in compatible Siemens/ITE bolt-on panelboards and loadcentres — including the Siemens/ITE EQ, ES, PL, and PN series that accept bolt-on three-phase devices. As a 3-pole, 35A, 240V unit, it is suited for commercial and light industrial three-phase branch circuit protection where a bolt-on style is required.

Bolt-on breakers are not interchangeable with plug-in style panels — confirm your panelboard accepts bolt-on devices before ordering. Send us your panel model number and we'll confirm compatibility.

The BQ (bolt-on) series physically mounts to the bus bar with a bolt, whereas plug-in breakers clip directly onto the bus stabs. These two mounting styles are not interchangeable — the BQ3B035 will only install correctly in a panelboard or loadcentre designed for bolt-on breakers. Always check your panel's inner door label or directory to confirm which style is required before ordering.

The Siemens BQ bolt-on series can be difficult to source as availability varies by region and stock levels. Northern Breaker Group specialises in obsolete and hard-to-find breakers and regularly supplies Siemens BQ series units across Canada from our Calgary, Edmonton, and Vancouver locations. Contact us for a quote and current availability.

The BQ3B035 (3-pole, 35A, 240V, 10kA interrupting capacity) is rated for three-phase branch circuit protection. Whether it can serve as a sub-panel feeder breaker depends on your specific panel configuration, load calculations, and local electrical code requirements (CEC). We recommend consulting a licensed electrician to confirm the breaker is appropriately sized and rated for your intended application.
