A.B Switch
A.B Switch – Air Break Switch It is a device that uses air as the dielectric,air break switches are widely installed throughout distribution network for use as both isolation or switching point, these switches are usually operated by a handle which is located at the ground level.
M.C.B
M.C.B – Miniature circuit breaker An electro-mechanical device designed to protect an electric circuit from overload or short circuit,whereas the circuit breaker disconnects the circuit at ON load connection.
Isolator
Isolator – An Isolator is a mechanical switching device. The Isolator disconnects the circuit at offload connection.
Feeder
Feeder – The power lines through which electricity is transmitted in power systems, Feeder transmits power from Generating station or sub-station to the distribution points.
