Applications

The HKIP disconnect knife switch is designed specifically for PV on grid distribution boxes and can also be used in various electrical setups in mines, offices, schools, rural power irrigation, and electric heating systems. The knife switch can be used to manually connect and disconnect circuits without frequent operation, while also offering short-circuit protection. With reduced capacity, the knife switch can also be used to control small AC induction motors for infrequent starting and stopping.
