The Siemens BQD6320 is a molded-case circuit breaker (MCCB) in the BQD frame, rated 3-pole, 20A, 600V AC with a 14kA interrupting capacity and a bolt-on mounting configuration. As an industrial/commercial-grade MCCB, it is designed to install in compatible Siemens panelboards and switchboards that accept BQD-frame bolt-on breakers — not in residential loadcentres.
- Mounting: Bolt-on; requires a panelboard or switchboard with BQD-compatible bus and breaker slots
- Voltage: Rated 600V AC, suitable for commercial and industrial distribution systems
- Interrupting Rating: 14kA at 600V — verify your available fault current does not exceed this rating

Yes. The BQD frame is a Siemens standard, so the BQD6320 is a direct form-fit replacement for other BQD-series 3-pole, 20A, 600V bolt-on breakers in the same panelboard or switchboard. Always verify that the ampere rating, pole count, voltage rating, and interrupting capacity match your application before swapping.
14kA at 600V is adequate for many commercial and light industrial distribution points, but you must confirm the available short-circuit current (ASCC) at the point of installation does not exceed 14kA. If your upstream fault current is higher, you'll need a breaker with a greater interrupting rating. An electrical engineer or utility can provide your available fault current — contact us if you need guidance selecting the right interrupting capacity.
Siemens BQD-frame breakers have seen limited availability as product lines evolve. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if the BQD6320 is no longer in active production, we can often source new-old-stock or factory-reconditioned units. Contact our Calgary, Edmonton, or Vancouver counter for current stock and lead time.
