BQD6330 - 30Amp Circuit Breaker

BQD6330 - 30Amp Circuit Breaker

The Siemens BQD6330 is a 3-pole, 30-amp circuit breaker used in 347/600VAC panelboard systems. It's commonly installed in commercial and industrial buildings where three-phase power is used for lighting, branch circuits, and general power distribution. For facilities already using Siemens panelboards, the BQD6330 is often selected for replacement work, system maintenance, and electrical upgrades where matching existing equipment is important.

This breaker features a thermal-magnetic trip unit and a 10kA interrupting rating, making it suitable for many everyday power distribution applications.

With a 30-amp rating and 3-pole configuration, the BQD6330 is well suited for protecting your three-phase circuits in office buildings, schools, healthcare facilities, warehouses, manufacturing plants, and similar properties operating on 347/600VAC electrical systems. Its panelboard-mount design allows it to be installed in compatible Siemens equipment without requiring changes to the existing system layout.
