QRH23B225 - 225 Amp Circuit Breaker

QRH23B225 - 225 Amp Circuit Breaker

Looking for a reliable, compact solution to protect your 240 V AC circuits? The QRH23B225 is a 3-pole, 225 amp thermal-magnetic breaker designed for commercial and industrial use. With a 25 kA interrupting capacity, it delivers dependable protection against overloads and short circuits, while its slim form factor (about 7″ height and 4.52 lb) ensures it fits cleanly into most panels. Built with a molded case and secure lugs already installed, this breaker makes installation fast—and its HACR approval means it’s ideal not just for general use but also HVAC and refrigeration systems.

Key Features and Benefits

• High Fault-Current Protection: 25 kA interrupting rating at 240 V gives you confident overcurrent protection.
