YL9-B+C surge protection device for AC 50/60Hz,385V and below the TN-S,TN-C,TN-C-S,TT,IT pwoer supply system,the power grid caused by lightning or surge voltage protection.
From the device failure
Module protector with failure from the device,when the protective device due to overheating,break down failure,the failure disengagement device can automatically detach it from the power grid,also give an indication signal.
