LT1 AC Contactor
PDF Download

LT 1 D contactors are alternating current contactors for control of circuits and consumers operating in class AC3. It is suitable for consumers with rated current up to 95A.The contactors are offered in a type with 1 NO contact for operating circuit making and the models over 40A also have 1NC operating contactor.

Functions
switching on/off heavy-loaded electrical circuits at controling signal to the coil
making of control systems
used as an operating element in process control panels
remarkable with high reliability of current characterstics
reliable separation of power contactors
secured cover of the movable part of the contactor
