BQ3B050 - 50Amp Circuit Breaker Description
BQ3B050 - 50Amp Circuit Breaker
The Siemens BQ3B050 is a 50 amp, 3-pole bolt-on circuit breaker used in compatible Siemens Type BQ panelboards and electrical distribution systems. With a 240VAC rating and a 10kAIC interrupting capacity, it is intended for three-phase branch circuit protection in commercial and industrial applications. Its common-trip design causes all three poles to open simultaneously when a fault is detected, helping protect your connected equipment and wiring.
This breaker includes load-side lugs and mounts directly into compatible panelboards using a bolt-on connection. It is commonly found protecting HVAC equipment, motor loads, pumps, compressors, control panels, and other three-phase circuits where a 50-amp breaker is required. When you're replacing an existing breaker, matching the original type, pole configuration, voltage rating, and amperage is important, and the BQ3B050 provides the form and fit expected from the Siemens Type BQ series.
