IS4P63 IMO Enclosed Rotary Isolators 63A 230 – 440V 4 poles
Why Choose the IMO IS4P63 Enclosed Rotary Isolator?
The IMO IS4P63 is a heavy-duty 63 A four-pole enclosed rotary isolator switch designed to provide safe and dependable electrical isolation for industrial, commercial and renewable energy applications. Housed within a durable IP65-rated flame-retardant enclosure, it offers excellent protection against dust and water ingress, making it suitable for both indoor and outdoor installations.
Designed for three-phase plus neutral electrical systems, the IS4P63 features a highly visible lockable red and yellow rotary handle, allowing operators to safely isolate equipment during maintenance and servicing. The enclosure incorporates an interlocked lid, preventing the enclosure from being opened while the switch is in the ON position, helping to improve operator safety.
With multiple cable gland knockouts, external mounting points and additional earth and neutral connections, the IMO IS4P63 offers straightforward installation across a wide range of industrial environments. It is widely specified by electrical contractors, panel builders and machine manufacturers where reliable local isolation is essential.
