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.
Product Benefits:
Isolator switch is used to ensure that an electrical circuit is completely de-energised for service or maintenance. IP66 enclosures and other options are available for your selection to meet a variety of inverters types. Such switches are often found in electrical distribution , where equipment must have its source of driving power removed for adjustment or repair. Isolation switches are used in electrical substations to allow isolation of apparatus such as circuit breakers, transformers, and transmission lines, for maintenance. The disconnector is usually not intended for normal control of the circuit, but only for safety isolation.
