QCR1030 - 30Amp Circuit Breaker

QCR1030 - 30Amp Circuit Breaker

The QCR1030 is a 30-Amp, single-pole thermal magnetic circuit breaker designed to provide dependable overcurrent and short-circuit protection in your 120VAC electrical systems. Built for applications requiring a compact DIN-rail or rear-mounted installation, this Type QCR circuit breaker combines reliable circuit protection with installation flexibility. Its thermal-magnetic trip mechanism responds to both prolonged overload conditions and instantaneous fault currents, helping you protect connected equipment and support the safe operation of electrical distribution systems. Featuring a 10kA interrupting capacity at 120VAC, HACR rating, and operation in 40°C ambient environments, the QCR1030 is well suited for commercial, industrial, OEM, and control panel applications where consistent performance and space efficiency matter. Its cable-in/cable-out design and compatibility with 35mm DIN rails make installation straightforward. At the same time, the slim profile allows it to fit neatly into panels where space is at a premium.
