This is an essential safety switch and is mandated in each photovoltaic power system according to IEC 60364-7-712. The corresponding British requirement comes from BS7671 - Part 712.537.2.1.1, which states "To allow maintenance of the PV convertor, means of isolating the PV convertor from the DC side and the AC side must be provided".
Product Profile
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.
