BQD6120 – SIEMENS 1P20A 347V BOLT ON 14kA BREAKER

The BQD6120 is designed for Siemens/ITE commercial and industrial bolt-on panelboards that support the BQD frame series and a 347 V bus. It is not intended for standard residential loadcentres. Because compatibility depends on your panelboard's specific bus design and available pole space, we recommend sending us your panel model number so we can confirm fit before ordering.

347 V is the phase-to-neutral voltage of a 347/600 V wye system, the standard high-voltage distribution system widely used in Canadian commercial and industrial buildings. It is most commonly used for lighting circuits, allowing longer wire runs with less voltage drop. If your facility operates on a 347/600 V system, the BQD6120 is the correct single-pole breaker voltage rating for branch circuit protection.

Availability of specific BQD series breakers can vary, and some configurations become difficult to source through standard distribution channels. Northern Breaker Group specialises in obsolete and hard-to-find breakers across Canada, with counter locations in Calgary, Edmonton, and Vancouver.
