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 Technical Data * Operation class:AC3 * Rated operating voltage of power contactors:up to 690V;50/60HZ * Composition of the power contact surfaces:unalloyed copper with coating 80% AgSnO * Surge voltage wear resistance:>8000V * Rated voltage of the coil voltage:from 0.8 to 1.15 Uc * Joining terminal:screw terminal * Connecting: - flexible conductors with or without cable terminal - rigid conductors * Electrical wear resistance (number of cycles):>=1000000 * Mechanical wear resistance (number of cycles):>=10000000 * Number of cycles per hour:1200UP TO 32A;600 for 40-95A * Pole leaking power:up to 13W * Mounting: - on DIN-rail or - with bolts to the surface - mounting position:vertical gradient-maximun±5o * Plastic:wear resistance of UV rays and non-flammable(self-extinguishing material) * Ambient temperature:-10oC+60oC * Altitude:up to 2000m Type a b ￠ LT1-D09~12 34/35 50/60 4.5 LT1-D18 34/35 50/60 4.5 LT1-D25 40 48 4.5 LT1-D32 40 48 4.5 LT1-D40~65 40 100/110 6.5 LT1-D80~95 40 100/110 6.5 Type Amax Bmax Cmax LT1-D09~12 47 76 82 LT1-D18 47 76 87 LT1-D25 57 86 95 LT1-D32 57 86 100 LT1-D40~65 77 129 116 LT1-D80~95 87 129 127
