1, ASD series products are not suitable for switch arc suppressing of AC load control.

2,When used in the occasion with voltage surge, we suggest to connect a overvoltage protection circuit in the 1,2 pins of this device, such as connect a voltage dependent resistor or RC absorbed circuit in parallel.
