BQ2B03000S01 - 30Amp Circuit Breaker

BQ2B03000S01 - 30Amp Circuit Breaker

The Siemens BQ2B03000S01 is a 2-pole, 30-amp thermal magnetic circuit breaker designed for your Type BQ electrical distribution equipment. In addition to standard overload and short-circuit protection, this breaker includes a factory-installed 120V shunt trip, allowing the breaker to be opened remotely when connected to a compatible control circuit. This feature is commonly used in emergency shutdown systems, safety interlocks, access control systems, and other applications where remote breaker operation is required.

Rated for 120/240 VAC with a 10 kAIC interrupting capacity, the BQ2B03000S01 is suitable for a variety of branch circuit applications. The common-trip mechanism disconnects both poles simultaneously, while the bolt-on connection and included load-side lugs support installation in compatible Siemens panels and loadcenters.
