Eaton WMZS3C25 Type C Miniature Circuit Breaker

Eaton WMZS3C25 is a Type C miniature circuit breaker rated at 25 A with a 10 kA breaking capacity, a compact protective device used to guard individual electrical circuits against overcurrents and short circuits within electrical distribution systems. It operates by automatically opening the circuit whenever the current exceeds its nominal rating or when a short circuit creates a fault current beyond the breaker’s interrupting capability, thereby helping prevent overheating and damage to wiring and connected equipment. The Type C trip curve indicates a balanced response that trips in the event of moderate overloads and instantaneous surges typical of general-purpose loads, making it suitable for many common residential and light commercial applications. A 10 kA short-circuit breaking capacity means the device can safely interrupt fault currents up to 10,000 A, a critical specification when coordinating with upstream protection and conductor ratings in the installation. The WMZS3C25 designation identifies this specific Eaton component within the miniature circuit breaker lineup, a standard choice for branch-circuit protection at 25 A in installations that require reliable overcurrent protection.
