The IMO IS4P20L is a robust 20 A four-pole enclosed rotary isolator switch designed to provide safe and reliable electrical isolation for industrial, commercial and building services applications. Housed within a durable IP65-rated polycarbonate enclosure, it is ideal for installations requiring a weather-resistant local isolator close to machinery or equipment.
Featuring a lockable red and yellow rotary handle, the IS4P20L enables operators to safely disconnect three-phase plus neutral circuits during maintenance and servicing. The enclosure incorporates an interlocked lid to help prevent accidental opening while the switch is in the ON position, supporting safe isolation procedures.
With its compact surface-mounted enclosure, multiple cable gland knockouts and external mounting points, the IMO IS4P20L offers straightforward installation across a wide range of industrial environments. It is commonly specified by electrical contractors, machine builders and panel manufacturers where dependable local isolation is essential.
Local isolator switches provide a safe means of disconnecting electrical equipment before maintenance or servicing. The IMO IS4P20L simultaneously isolates all four conductors, making it suitable for three-phase plus neutral installations where complete circuit isolation is required.
Its lockable rotary handle and robust IP65 enclosure make it particularly suitable for factories, workshops, HVAC installations and outdoor plant where dependable electrical isolation and environmental protection are essential.
