Isolators are suited to a huge range of applications. Regular switching requirements are more than adequately handled by our proven "Standard" 3 or 4 pole devices, while dedicated designs are available for switching DC loads, PV applications and Battery Banks - see our Solar Isolators.

IMO offers a comprehensive range of high-quality AC Isolators with switching capabilities ranging from 20A to 125A, both in 3 and 4 Poles. Within the range, there are a number of different mounting types including Panel Mount, DIN Rail Mount and Enclosed, plus there are a range of handles and extendable shafts to suit most applications, as well as other accessories to compliment the range. The handles can be locked in the OFF position for peace of mind when maintenance is taking place.
