BQ2B080H - 80Amp Circuit Breaker

BQ2B080H - 80Amp Circuit Breaker

The Siemens BQ2B080H is an 80-amp, 2-pole molded case circuit breaker designed for use in 120/240V electrical distribution systems. It provides overcurrent protection for your wiring, equipment, and connected loads by helping prevent damage caused by overloads and short circuits. The common-trip mechanism disconnects both poles simultaneously during a fault, making it suitable for applications that require reliable two-pole protection.

Part of the Siemens BQH breaker series, the BQ2B080H features a bolt-on connection and includes load-side lugs to simplify installation. Its 22 kA interrupting rating allows it to be applied in systems with higher available fault current, while the compact design makes it a practical choice for your panelboards, load centers, and other distribution equipment where space is limited.
