Eaton WMS3D06 6A 3-Pole 480 V Circuit Breaker

Meet the Eaton WMS3D06 — a rugged 3-pole circuit breaker engineered for dependable protection in 3‑phase electrical systems rated up to 480 V. With a precise 6 A current rating, this device guards small feeders and control circuits without unnecessary interruptions, helping keep downtime to a minimum.

Designed for reliability, the WMS3D06 disconnects all three active conductors in the event of an overcurrent or fault, offering coordinated protection across phases. This reduces the risk of partial fault scenarios that can stress equipment and complicate fault diagnosis.
