IEC 60947-6-1 WATSN Compliant 100-630A Weatherproof Distribution Box electromagnetic field Level 3

IEC 60947-6-1 WATSN Compliant 100-630A Weatherproof Distribution Box electromagnetic field Level 3

Schneider Wingoal Made

Class PC

• Transfer switch equipment based on mechanical switching devices, that do not need electrical power to hold the main contacts open or closed and capable of making, carrying, and breaking currents under normal circuit conditions including operating overload conditions, and making and withstanding short-circuit currents.

WATSN automatic transfer switch is specially designed in accordance with the standard requirements for power transfer. It does not provide protection but has a great withstanding and connectivity capacity. In other words, it can guarantee the safety of switch itself, and will not be damaged due to failure such as overload or short circuit, thus keeping a reliable connectivity of circuits.
