The WRS4P40 is a 40A 4 pole AC rotary isolator housed in a durable IP65-rated enclosure. It provides safe and reliable disconnection of single or three-phase AC circuits, isolating all live conductors (L1, L2, L3, N) to ensure compliance with BS 7671 maintenance and emergency requirements.
Its red/yellow rotary handle offers clear ON/OFF indication, while the padlock option allows secure lock-off during servicing. The 40A rating makes it a versatile choice for EV charge points, plant equipment, and commercial distribution boards.
Installer Tip: Use the 40A model for higher demand EV chargers or commercial submains where a 32A isolator may be undersized. Always confirm cable sizing for 40A loads.
