Q350H - 50Amp Circuit Breaker

Q350H - 50Amp Circuit Breaker

Looking for a Q350H circuit breaker and want to make sure the specifications match your application? The Q350H 50-amp, 3-pole Type QPH circuit breaker combines a compact plug-in design with a 22kAIC rating at 240VAC, making it a practical choice for compatible electrical distribution equipment requiring this specific breaker configuration. With three poles and a 50-amp rating, it is well suited to compatible three-phase applications where dependable overcurrent protection is required. The breaker is also HACR rated and carries a 40°C rating, adding versatility for qualifying heating, air-conditioning, and refrigeration applications. At approximately 3.13 inches high, 3.0 inches wide, and 2.56 inches deep, the Q350H packs its circuit-protection capabilities into a compact footprint. Whether you're replacing an existing Q350H or matching a breaker to compatible equipment, the important details are easy to verify: 50 amps, 3 poles, Type QPH, plug-in mounting, and 22kAIC at 240VAC. Always confirm these specifications against your equipment requirements before installation.
