QDP22125TM - 125 Amp Circuit Breaker

QDP22125TM - 125 Amp Circuit Breaker

The QDP22125TM PowerPact Q circuit breaker is a 125-amp, 2-pole breaker built for your overcurrent protection and switching in 240VAC electrical distribution systems. It combines thermal and magnetic trip protection to respond to both overloads and short-circuit conditions, making it a dependable choice for commercial and industrial applications.

One of the advantages of the PowerPact Q series is its straightforward design and proven performance. The thermal-magnetic trip unit allows normal equipment startup currents to pass without unnecessary tripping while still providing fast protection when fault conditions occur. With a 25kA interrupting rating, the QDP22125TM helps you limit damage caused by high fault currents and protects connected equipment from more serious electrical issues.

This breaker features a unit-mount design with line-side terminal nuts and load-side lugs for secure installation. A built-in push-to-trip button allows technicians to manually trip the breaker during testing and maintenance procedures. The breaker is also HACR rated, making it suitable for many HVAC and refrigeration applications.

Commonly used in distribution panels, control equipment, feeder circuits, and industrial electrical systems, the QDP22125TM delivers the protection and reliability needed to keep electrical systems operating safely.
