Contactors LT 1- Dxx
Contactors LT 1- Dxx series are designed to control alternating current circuits with rated current from 9 to 95A. The power contacts are made of pure copper with galvanic coating of 80%AgSnO. The magnetic core is made of steel alloy 360 type and the movable part to which the contact systems are mounted – of bakelite, which allows high reliability of current characteristics, electrical endurance from 1 000 000 cycles, and mechanical endurance from 10 000 000 cycles. The pole leaking power is up to 13W which allows frequently switching on/off up to 1200 n/h for contactors up to 32A and 600n/h for contactors from 40 to 95A. The contactors corpus plastic is remarkable with high mechanical strength, endurance of UV rays and non-flammable. All contactors are designed in a type with three power contacts with rated current from 9 to 95A and auxiliary contacts for contactors up to 32A, including 1NO or 1NC, and for the models from 40 to 95A – 1NO and 1NC. They are offered in types with voltage of the controlling coil from 12 to 400V AC which may vary from 0.8 to 1.15Un. The rated operating voltage of power contactors is up to 690V, 50/60Hz and the plastic impulse voltage endurance is 8000V. An additional auxiliary block can be mounted to all contactors from LT 1- Dxx series.
