For isolating, selecting or controlling electrical equipment

    Isolation and Changeover Switches

    DC & AC switches for isolating generation or loads, or to select and changeover between AC loads or sources - eg. From automatic operation to manual operation or off for servicing.

    DC Isolators

    These are used between high voltage DC PV arrays and grid-connect inverters. They are located adjacent to the inverter and are required to provide a means of manually isolating the entire PV array during system installation or any subsequent maintenance.  The switch must be rated for system voltage (1.15 x string open circuit voltage Voc) and current (1.25 x string short circuit current Isc). 

    AC Isolators

    These are required to provide a means of manually isolating the AC supply to a grid-connect inverter. Two AC isolation switches may need to be provided between the inverter and the point of connection to the supply. One adjacent to the inverter and one adjacent to the consumer unit (Only one is needed if in the same room). The one adjacent to the consumer unit must be readily accessible and capable of being locked in the off position only. Switches must be double pole and suitably labelled.
