The Siemens BQ2B090H is a bolt-on style breaker from the Siemens BQ/BL/BA series, designed to mount in compatible Siemens/ITE bolt-on panelboards and loadcentres — typically the Siemens/ITE EQ, ES, PL, and PN series panels that accept bolt-on breakers. As a 2-pole 90A unit, it occupies two tandem spaces and is suited for branch or feeder circuits up to 240V AC with 22kA interrupt rating.
Bolt-on breakers are not interchangeable with plug-in loadcentres — always verify your panel accepts bolt-on devices before ordering. Send us your panel model number and we'll confirm fit.
Bolt-on breakers like the BQ2B090H physically bolt to the bus bar rather than clipping on, which provides a more secure connection in commercial or high-vibration applications. They are only compatible with panelboards specifically designed for bolt-on devices (such as certain Siemens/ITE EQ, ES, PL, and PN series panels). If your panel uses plug-in breakers, the BQ2B090H will not fit. Check your panel's label or send us the model number and we'll verify compatibility for you.
The 'H' suffix on Siemens BQ-series breakers typically denotes a higher interrupt rating. In this case, the BQ2B090H is rated at 22kA short-circuit current rating (SCCR), which may differ from a base-model variant. Always confirm the interrupt rating required by your system's available fault current — if you're unsure, our team can help you cross-reference the correct breaker for your application.
Siemens BQ-series bolt-on breakers can be difficult to source as the product line has seen limited availability through standard channels. Northern Breaker Group specialises in obsolete and hard-to-find breakers across Canada, so even if this unit is discontinued or backordered elsewhere, we may have stock or a verified equivalent. Contact our Calgary, Edmonton, or Vancouver locations for availability and lead times.
