QS2225H - 225A Circuit Breaker

QS2225H - 225A Circuit Breaker

The QS2225H is a 225 amp, 2-pole thermal magnetic circuit breaker designed for use on 120/240VAC electrical systems. It combines thermal overload protection with an instantaneous magnetic trip to help protect electrical equipment from overloads and short circuits before they become costly problems. With a 22kA interrupting rating, the QS2225H is well suited for commercial and industrial power distribution where dependable overcurrent protection is required. It's also HACR rated for 60Hz applications, making it a solid choice for heating, air conditioning, and refrigeration equipment. One feature electricians appreciate is its wide conductor range. The breaker accepts #3 AWG through 300 kcmil copper or aluminum wire, making it easier to match existing installations without unnecessary modifications. A 40°C ambient rating allows it to perform in a variety of operating environments. If you're replacing a worn breaker or servicing an electrical distribution panel, the QS2225H offers the electrical ratings professionals look for while helping keep connected equipment protected and operating as intended.
