BQ2B030H - 30Amp Circuit Breaker

BQ2B030H - 30Amp Circuit Breaker

The Siemens BQ2B030H is a 2-pole, 30-amp thermal magnetic circuit breaker designed for you to use in Type BQH loadcenters. The common-trip mechanism disconnects both poles during overload and short-circuit conditions. Rated for 120/240 VAC with a 22 kAIC interrupting capacity, this breaker is used in residential, commercial, and light industrial electrical distribution systems.

The BQ2B030H features a bolt-on connection and includes load-side lugs. Common applications include HVAC equipment, air conditioning systems, water heaters, small motors, dedicated appliance circuits, and other branch circuits requiring a 30-amp two-pole breaker. Its molded case construction is intended for installation in compatible Siemens electrical equipment.
