The WRS4P20 is a compact 20A 4 pole AC rotary isolator housed in an IP65 weatherproof enclosure. Designed for safe isolation of single or three-phase AC circuits, it provides secure disconnection of all live conductors (L1, L2, L3, N) during maintenance or in an emergency.
With a clear red/yellow rotary handle and positive ON/OFF indication, this isolator is easy to operate and lockable for added safety. It is ideal for EV chargers, outdoor submains, and general AC isolation tasks up to 20A.
