WNA Series Dual-power Automatic Transfer Switches

WNA Series

INTRODUCTIONIn order to satisfy AC-33A use category, WNA series dual-power automatic transfer switches adopt such designs as the structure of three contacts, separate movable and stationary contact (split type), and interlocked contact (to limit position) and so on. Each pole has independent making and breaking indication. Incoming and outgoing line are exchangeable.
