WNA Series
WNA Series

INTRODUCTION

In 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.

FURTHER INFORMATION
WNA series switches are applied to various important occasions of high reliability and security such as data centers, power plants, airports, hospitals, communications and petroleum sites. Used with the WST-5 and WST-6 controller, it is capable of multi-functional conditional transfer. Products of superimposed connected center line transfer function are its derivatives.
