LS Susol vacuum contactors are mainly used for the switching of motors, transformers, capacitors in AC power lines. When more than certain amount of excess current flows in the load by overload relay, MS detects and OFF the operation power of MC to stop the load. A vacuum It is used to protect/control the load by ON/OFF of MC which starts/halts the motor load. They can be installed in multistack cubicles.
