Electrical Contactor, Switch, Circuit Breaker ... Breaker interrupts the fault current which electrical contactor cannot. Generally contactors are connected in series with fuse. Therefore during short circuits fuse acts as fault current interrupting element in the circuit. In simple contactor is a switch with remote control and automatic functions.

High-Voltage Compact Switchgear· PDF file6 gas-insulated and air-insulated components. According to CIGRE analyses, gas-insulated components are four times more reliable than air-insu-lated components. By increasing the safety of our product through the separation of gas compartments (e.g. between the circuit breaker and disconnector), we increase availability of switchgear in the market.
