The Timeguard IS3N-20AC 20A 3 Pole AC Rotary Isolator Switch provides reliable local isolation for AC electrical circuits in commercial, industrial and outdoor installations. Designed for safety, durability and straightforward wiring, this weatherproof rotary isolator is suitable for applications where a secure lockable switch disconnector is required.
The tough thermoplastic enclosure offers strong protection for demanding environments, while the IP66 rating provides total protection against dust and high-pressure water jets from any direction. Multiple M25 threaded cable entry knockouts and a large enclosure help make wiring easier for installers, especially where larger cable runs or practical cable access are required.
For added safety, the tamperproof rotary switch can be locked in position, helping prevent unauthorised operation. The interlocked front cover can only be removed when the switch is in the OFF position, supporting safer installation and maintenance. The switch can also be removed from the DIN rail assembly for easier first fix and wiring.
With rising clamp terminals supporting cable up to 16mm², BS EN IEC 60947-3 compliance and a 3-year manufacturer guarantee, the Timeguard IS3N-20AC is a dependable 20A 3 pole isolator switch for electricians, contractors and facilities maintenance teams.
