Product Description

Product Description

 

Professional Solar DC Isolator Manufacture

 

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.

Isolators are generally rated for AC1/AC21 while for motor applications they need to be rated for AC3/AC23A duty.
Applications: Switching of main/control and instrumentation circuits motor ON-OFF and other special application circuits.
