Product Description
Description of auto switches
WP523 universal changeover switch is an manual transfer switch , assure the changing of power supply, low voltage circuit with load etc.It widely used for controlling three phase asynchronism electromotor, can replace every different change over switch .
Function of auto switches
==>The switch are manual multipolar changeover switches
==>The provide changeover,source inversion or switching underload between two low voltage power circuits,as well as their safety isolation.
General charateris teristics of auto switches
==>Fully visualised breaking
==>Fully integrated bridging bars
