The Cutler-Hammer QCR1045 is a 45 A, 240 V, single-pole circuit breaker designed for DIN rail mounting in industrial electrical panels and control enclosures. It provides overcurrent protection for a single circuit and is suitable for use in compact control cabinets and distribution panels where quick installation and secure mounting are important. This DIN rail mounted device is part of the Cutler-Hammer QCR family and is intended for use on 240 VAC, single-phase circuits in industrial environments. Typical applications include protecting small to mid-size single-phase loads in industrial automation, machinery enclosures, and control panels where a 45 A rating is appropriate.
