ISOLATOR
|
CIRCUIT BREAKER
|
Isolator is meant only for interrupting the power during maintenance or repair.
|
Circuit breakers are meant for protection of a circuit or equipment from short circuit and overload faults while they are in operation.
|
Isolators and Disconnectors are types of simple mechanical switch.
|
Circuit Breaker consists of electromechanical switch and a relay in a single box.
|
Atmospheric Air is used as arc quenching medium
|
Different kind of medium are used typically atmospheric air, SF6 and Vacuum
|
It is a Mechanical device which acts as a switch.
|
It is an Electronic device made by using MOSFET or BJT.
|
Isolators can be operated only during offload
|
Circuit breakers can be operated during both on-load and offload.
