LW15 Series universal change-over switch

Purpose
Universal change-over switch is mainly applied to change-over electric control circuit and electric measurement meter in the electrical
circuits (AC 50Hz, voltage 380V and below, DC voltage 220V and below). It also can be used to directly control small capacity three-phase AC
cage induction motor for starting, reversible change-over and speed variation.

Model and meaning: When used for master control, model requires to be filled out as follows
