What is an electrical isolator?
Electrical isolator or disconnector is a type of mechanical switch that is used in electric circuits and devices with the main function of effectively isolating two different parts of an instrument or power circuit. By definition, isolation is the process of complete separation of various parts of an apparatus and this separation can either be physical or electrical or both.
Electrical Isolator switches are used for opening an electrical circuit in the no-load condition. It is not proposed to be opened while current flows through the line. Generally, these are employed on circuit breaker both the ends thus the circuit breaker repair can be done easily without any risk.
