LKF-transformer-protection-switch-box
Product Overview The transformer protection switch box uses intelligent components to detect the operating current, which can accurately judge the relevant electrical operating conditions. In the event of: overload, short circuit, overvoltage, current imbalance, phase failure, leakage, etc., the smart device can trip within 0.2 seconds according to the above conditions, and automatically reclose the switch about 10 seconds after tripping. If the fault disappears, the normal power supply will be restored, which can effectively protect the transformer and electrical appliances....
