W-2 is a two-stage automatic transfer switch. After a switching signal is received the switch transfers power immediately from one source to the other without stopping at an OFF position in the middle. The rated current is 20A~500A.
The WN3 is a three-stage automatic transfer switch. After a switching signal is received the switch transfers power immediately, or after a preset delay, or stop at an OFF position in the middle. The rated current is 20A~5000A.
