BQ3B080 - 80Amp Circuit Breaker

BQ3B080 - 80Amp Circuit Breaker

The Siemens BQ3B080 is an 80-amp, 3-pole circuit breaker used in 240-volt electrical distribution systems. It is part of Siemens' Type BQ breaker line and is designed to provide overcurrent protection for branch circuits, feeder circuits, and other three-phase applications. The common-trip mechanism opens all three poles at the same time when a fault is detected, helping protect your conductors and connected equipment.

This breaker uses a bolt-on mounting design and comes with load-side lugs included. With a 10 kA interrupting rating and UL 489 listing, the BQ3B080 is suitable for many commercial and light industrial electrical systems. It is commonly found in panelboards, load centers, HVAC equipment, and power distribution systems where an 80-amp, 3-pole breaker is required.

For contractors, maintenance personnel, and facility managers working with Siemens equipment, the BQ3B080 offers a straightforward replacement or installation option that matches the specifications required for compatible electrical systems.
