Direct control wiring is for single-phase powered electrical appliances with lower power consumption than load capacity of this switch. Picture 2. Single phase expansion wiring is for single-phase powered electrical appliances with higher power consumption than load capacity of this switch. You will need an alternating current contactor with more capacity than the electric power consumption to expand capacity. Picture 3. Three-phase wiring is for three-phase electrical appliances, with a AC220V, 50Hz control contactor coil voltage, you will need a external three-phase AC contactor. Picture 4. Three-phase wiring is for three-phase electrical appliances, with a AC380V, 50Hz control contactor coil voltage, you will need a external three-phase AC contactor.  Package Includes: 1 x Timer Switch Note:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
