Why Choose the IMO IS4P32L Enclosed Rotary Isolator?

The IMO IS4P32L is a heavy-duty 32 A four-pole enclosed rotary isolator switch designed to provide safe, reliable local isolation for industrial machinery, commercial installations and electrical distribution systems. Supplied in a durable IP65-rated polycarbonate enclosure, it offers dependable protection against dust and water ingress, making it suitable for both indoor and outdoor applications.

Featuring a highly visible lockable red and yellow rotary handle, the IS4P32L enables safe isolation of three-phase plus neutral circuits during maintenance and servicing. The enclosure incorporates an interlocked lid, preventing access while the switch is in the ON position and helping to improve operator safety.

Designed for straightforward installation, the enclosure includes external mounting points, multiple cable gland knockouts and an additional earth connection. Its compact yet robust construction makes it a popular choice for machine builders, panel manufacturers and electrical contractors requiring dependable local isolation.
