BQ3B080H - 80Amp Circuit Breaker

BQ3B080H - 80Amp Circuit Breaker

The Siemens BQ3B080H is an 80-amp, 3-pole molded case circuit breaker used in 240V three-phase electrical distribution systems. It features a common-trip design that opens all three poles simultaneously when an overload or short circuit occurs. The breaker is part of Siemens' Type BQH product line and is commonly installed in panelboards, load centers, and distribution equipment that require an 80-amp, 3-pole breaker with a higher interrupting rating.

This model carries a 22 kA interrupting capacity and includes load-side lugs from the factory. The bolt-on connection provides a secure installation in compatible Siemens equipment. Its compact footprint makes it suitable for branch circuits, feeder circuits, HVAC equipment, and other commercial or light industrial electrical applications where space inside the panel may be limited.

Whether you're using it as a replacement breaker or installed as part of a new electrical distribution system, the BQ3B080H provides the ratings and configuration required for many three-phase applications. Like other Siemens molded case breakers, it is built for long-term service in everyday operating conditions.
