Eaton WMZT2C03 Molded Case Circuit Breaker Type C

The Eaton Cutler-Hammer WMZT2C03 is a double-pole molded-case circuit breaker (Type C) with a 3 A nominal rating and a 10 kA interrupting capacity, UL489-listed, designed for use in protected electrical distribution systems. As a UL489-listed Type C device, it provides overcurrent protection in two-pole configurations, capable of interrupting fault currents up to 10,000 A to safeguard downstream conductors, equipment, and connected devices. The WMZT2C03 designation identifies this model within Eaton's WMZ family and confirms its two-pole form factor, Type C tripping characteristics, and Cutler-Hammer lineage, ensuring consistent performance and interchangeability with other WMZ-type devices. This specific part provides controlled disconnection under overload or short-circuit conditions, protecting circuits designed to operate at 3 A while accommodating brief surges encountered in normal operation, and it is intended for use in compatible electrical panels and enclosures. The 10 kA interrupting capacity establishes a ceiling for fault current handling, giving installers a clear specification for selecting protection devices that meet safety standards while maintaining compatibility with standard electrical enclosures accepting molded-case breakers.
