Timeguard IS4N-63AC Weathersafe Grey 63A IP65 4-Pole Rotary Isolator Switch

Timeguard IS4N-63AC Description

The Timeguard IS4N-63AC AC Rotary Isolator Switch provides robust, manual isolation for 63 A AC circuits, making it suitable for high-load electrical distribution, maintenance shut-off points, motor feeds and multi-phase power systems. It features a weatherproof thermoplastic enclosure with an IP66 rating, ensuring protection against dust ingress and powerful water jets — ideal for exposed indoor and outdoor use where environmental protection is essential.

Designed with both installer convenience and safety in mind, the IS4N-63AC includes multiple M25 cable entry threaded knockouts for flexible cable routing, rising clamp terminals typically supporting up to 16 mm² cable sizes, and on-load switch disconnectors to allow safe disconnection under load. The lockable rotary switch helps deter unauthorised operation, and the interlocked front cover can only be removed when the switch is in the OFF position, adding an extra layer of user protection during wiring and maintenance.

With its durable construction, spacious enclosure for easy wiring, and Timeguard’s 3-year guarantee, the IS4N-63AC delivers proven performance and peace of mind in heavy-duty electrical systems.
