Protect STS Static Transfer Switch

Static Transfer Switches (STS) transfer supply between independent one-phase or three-phase AC power sources. Unlike traditional automatic transfer switches (ATS), Static Transfer Switches (STS) provide 20 times faster load transfer, which ensures the uninterrupted operation of even the most sensitive electronic equipment. Load retransfer to preferred input source is virtually instantaneous.
