Overview
The Eaton WMZT3C10 is a 10A, 3-pole miniature circuit breaker rated for 277/480V VAC with Type C trip curve characteristics. UL 489 listed and designed for 35mm DIN rail mounting, the WMZT3C10 delivers current-limiting protection, interrupting fault currents within one half-cycle of the fault to reduce peak let-through energy. This device is ideal for branch circuit protection in industrial control panels and pilot devices.
Key Features
- 10A rated current with Type C trip curve (5–10× In magnetic threshold)
