Q370 - 70Amp Circuit Breaker

Q370 - 70Amp Circuit Breaker

Looking for a Q370 70-Amp, 3-pole circuit breaker and want to make sure the specifications line up with your application? The Q370 is a Type QP plug-in circuit breaker rated for 70 amps, with three poles and an interrupting rating of 10 kA at 240 VAC. Its plug-in configuration makes it a practical choice for compatible electrical distribution equipment that accepts this breaker type. It's also HACR rated, an important consideration for compatible heating, air-conditioning, and refrigeration applications. Measuring 3.13 inches high, 3.0 inches wide, and 2.56 inches deep, the Q370 packs its three-pole protection into a compact footprint. Whether you're replacing an existing Q370 or matching a breaker to compatible equipment, the key is getting the specifications right. Check the part number, amperage, number of poles, voltage, A.I.C. rating, dimensions, and breaker type against your existing equipment before installation.
