BQ2B080 - 80Amp Circuit Breaker

BQ2B080 - 80Amp Circuit Breaker

The Siemens BQ2B080 is an 80-amp, 2-pole molded case circuit breaker designed for 120/240V electrical distribution systems. It helps protect wiring, equipment, and connected loads from overloads and short circuits while providing the reliable performance expected in residential, commercial, and light industrial installations. The common-trip design disconnects both poles simultaneously during a fault, helping maintain system safety and proper circuit protection.

Part of Siemens' BQ breaker family, the BQ2B080 features a bolt-on connection and includes load-side lugs for straightforward installation. Its compact footprint allows it to fit comfortably in panelboards and distribution equipment where space may be limited. With a 10 kA interrupting rating, this breaker is suitable for a variety of branch and feeder circuit applications.

Whether you're replacing an existing breaker, upgrading a panel, or completing a new installation, the BQ2B080 provides dependable overcurrent protection for everyday electrical distribution needs. It is commonly used in offices, retail buildings, apartment complexes, schools, HVAC systems, and light industrial facilities where consistent circuit protection is essential.
