QCR2020 - 20Amp Circuit Breaker

QCR2020 - 20Amp Circuit Breaker

The QCR2020 is a 20-amp, 2-pole thermal-magnetic circuit breaker designed to provide dependable overcurrent and short-circuit protection in your 120/240 VAC electrical systems. Featuring a 10kA interrupting capacity (A.I.C.), this Type QCR breaker combines reliable performance with a compact footprint, making it an excellent choice for commercial, industrial, and OEM electrical applications. Its thermal magnetic trip mechanism helps you protect connected equipment from overloads and fault conditions while supporting consistent operation in environments rated up to 40°C (104°F). Designed for installation on 35mm DIN rails or via rear mounting, and featuring cable-in/cable-out connections, the QCR2020 offers installation flexibility for new equipment, control panels, and replacement projects. Additionally, its HACR rating makes it suitable for heating, air conditioning, and refrigeration equipment where applicable.
