The Eaton Cutler-Hammer QCR1010 is a 1-pole, 10-amp circuit breaker designed for 120/240-volt electrical systems, identified by the part number QCR1010 and the Type QCR designation. It provides overcurrent protection with a 10,000-amp interrupting capacity (10kAIC), enabling it to interrupt high fault currents to safeguard conductors and connected devices. This device is configured for single-pole operation at 120/240 V and is used to protect a single branch circuit from overloads and short circuits. As part of the QCR product line, the QCR1010 embodies Eaton's approach to reliable overcurrent protection within distribution panels that accommodate Type QCR breakers.
