This indoor high voltage load switch is the FZN25 and FZRN25 model from Anqiang Electric Power. It is suitable for three-phase AC 50Hz ring network and terminal power supply and industrial equipment, serving as a load control and short-circuit protection device. The load switch is used for switching loads, closing loop currents, and switching no-load transformers and cable charging currents; the combined switch can interrupt any current up to the rated short-circuit current. Indoor High Voltage Load Switch adopts a direct-acting isolating contact and vacuum interrupter linkage, and features both manual and electric operation.
