IMO's range of AC Isolators are available in a range of mounting options including Enclosed, Base Mount, Direct Handle Base Mounted and Front Panel Mount, and are available in a variety of pole configurations to be used in stand-alone grids or network distributed systems. All IMO AC Isolators are UL approved and are constructed from the same high quality materials that our market-leading SI range are renowned for. All IMO isolators are capable of being installed in areas where high ambient temperatures of up to +45ºC can be found. Unlike a DC isolator that is required to switch both the positive and negative conductors, an AC isolator should be chosen with regards to the supply being single phase, which is typically found in domestic installations or three phase, which is typical for commercial or industrial installations. Ideally for single phase a 2 pole isolator should be used to switch the live and neutral line (earth constantly connected) whilst a 4pole isolator would be used to switch the 3 voltage lines and neutral (earth constantly connected).
