ONCCY DC Isolator is Designed for solar inverter DC side disconnect, Combined with other components, our switches can guarantee complete protection from any form of over-voltage and overloading. With a special instruction for arc extinguishing, we offer increased safety, reliability and longer life.
PV Isolator Switches are ON-OFF Switches to isolate the power to a particular area of operation. The Isolator Switches are offered in a wide range from 1 Pole to 10 Poles. Isolators with spring return upto 4 Poles are available to energise circuits. Isolators with pre-close contacts are used for safety circuits and for connecting neutral and earth lines.
