Cutler-Hammer HKW4200V Molded Case Circuit Breaker

Cutler-Hammer HKW4200V molded case circuit breaker is a 200 A, 690 V protective device designed to interrupt fault currents and protect electrical circuits from overloads and short circuits. The HKW4200V designation identifies the model and voltage/current ratings for reliable overcurrent protection in electrical distribution systems. As a molded case circuit breaker (MCCB), it provides the essential function of opening the circuit when current exceeds its rating, helping prevent damage to conductors and equipment. Manufactured by Cutler-Hammer, this device is intended for installations that require robust overcurrent protection at up to 200 A and 690 V. Use cases typically involve protection of feeders and circuits within industrial or commercial panels, where reliable interruption of fault currents is required to maintain safe and compliant operation.
