The BQD340 is a reliable Siemens 3-pole circuit breaker designed for heavy-duty applications. With a 40A current rating and 480V voltage capacity, it efficiently protects your electrical systems. Featuring a robust 14kA short-circuit rating, this bolt-on breaker ensures safety and performance, making it an ideal choice for industrial environments.
The BQD340 is a bolt-on MCCB intended for commercial and industrial Siemens BQD-series compatible panelboards and switchboards rated for 480V systems. It is not designed for residential loadcentres. Contact us with your panelboard model to confirm compatibility.
Availability can vary as the BQD frame is an older Siemens series. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if the BQD340 is no longer in active production, we can often source new, reconditioned, or equivalent units. Reach out to one of our Calgary, Edmonton, or Vancouver counters for current stock.
A direct replacement requires matching the frame series, bolt-on style, pole count (3P), amperage (40A), voltage rating (480V), and interrupting rating (14kA minimum). The BQD340 is the correct like-for-like replacement for an existing BQD340. If you're cross-referencing from a different brand or frame, send us the original breaker details and we'll help identify a suitable replacement.
