AC Isolator switches are devices or systems that isolate a particular circuit for maintenance and prevent currents from passing through. The main isolator switch, also known as an isolator, typically consists of two sets (or one set) of electrical contacts mounted in series. The line side is connected to a power supply outside the building.
AC Isolator Switch ensure an electrical circuit is completely de-energised for routine service and maintenance and can be shut down quickly in the event of an emergency. The switch separates the circuit from the main power source and discharges any current trapped in the circuit, rendering it safe to work on and ensuring fast shut down and the absence of any electrical current when an emergency stop is required.
