Electrical Isolator switch

Have you ever been heard about electrical isolator switch? Well just think about a ON and OFF switch that you see everywhere in your house. The electrical isolator switch behave like your house switch. But this isolator switch is big in size and very protective from chemical and mechanical accident. Confuse right?!!! Well let go through about this.

Electrical Isolater switch is a electrical application to switch ON and OFF circuit in place likely accident happen. So this switch is build i big sizes and strong material to width stand accidents. There are many types of electrical isolator. Lets look out.

1) Single phase Isolater

a)

 b)

This isolater is used for single phase unit like high horsepower air conditioner,air compressor and some heavy single phase electrical unit.

2) Three Phase Isolater

a)

 

b)

This three phase electrical isolator switch is used for heavy three phase electrical unit like heavy duty industrial machine. So this is the best way to use this isolator to turn ON and OFF safetly. The picture 'B' shown above is also a isolator called 'Rotary Isolator' Like a classic switch is isolator used to turn clockwise to ON and counter clockwise to turn OFF.

3) Isolating pole switch

This isolator switch is look like a MCB,but it is a great device to discconect single phase and three phase connection in safe way. This switch is determine by how many poles are in the switch. For example, A 3 pole isolator has three connection for three phase. A 4 pole isolator has 4 connection for three phase and neutral.

Electrical Isolator switch Wiring

The wiring for this electrical wiring is simple and easy to understand. 

ON stage : The isolator connect together

OFF stage : The isolator disconnect together
