Eaton WMZS3D03 is a three-pole miniature circuit breaker rated for 277/480 VAC, with a 3 A nominal current rating and a 5 kA interrupting capacity. The three‑pole design protects all three phases in a 277/480 VAC system, making it suitable for industrial or commercial panelboards and distribution that require three‑phase overcurrent protection. It trips to interrupt current during overloads or short circuits, helping prevent damage to wiring and equipment.
