BQ2B030 - 30Amp Circuit Breaker

BQ2B030 - 30Amp Circuit Breaker

The Siemens BQ2B030 is a 2-pole, 30-amp thermal magnetic circuit breaker for your Type BQ electrical distribution equipment. The common-trip design opens both poles during overload and short-circuit conditions. Rated for 120/240 VAC with a 10 kAIC interrupting capacity, this breaker is used for branch circuit protection in residential, commercial, and light industrial applications.

The BQ2B030 features a bolt-on connection and includes load-side lugs. Common installations include air conditioning equipment, water heaters, small motors, workshop equipment, dedicated appliance circuits, and other loads requiring a 30-amp two-pole breaker. Its molded case construction is intended for use in compatible Siemens loadcenters and panelboards.
