BQD6350 – SIEMENS 3P50A 600V BOLT ON 14kA BREAKER

The BQD6350 is a bolt-on MCCB designed for commercial and industrial panelboards and switchboards that accept Siemens BQD-frame breakers rated at 600V. It is not a residential loadcentre breaker. Because compatibility depends on your panel's bus spacing and frame, we recommend sending us your panelboard model number so we can confirm fit before ordering.

At 14kA at 600V, the BQD6350 is suited for many light commercial and industrial distribution applications where available fault current is at or below that threshold. For installations with higher available short-circuit current, a higher-rated interrupting capacity breaker would be required. If you're unsure of your system's available fault current, consult your electrical engineer or contact our team for guidance.
