Design and technical parameters

The TeSys D contactor is designed for durability and ease of use. The use of high-quality materials ensures resistance to environmental conditions and long device life. The operating voltage for AC is 440V (50/60Hz), and the control voltage type is AC. This makes the contactor compatible with most standard power systems. Integrated auxiliary contacts are adapted to signals with a minimum current of 1 mA, allowing them to be connected directly to PLCs. In addition, a wide range of accessories are available to adapt the contactor to specific application requirements – additional auxiliary contacts are dust-resistant and designed for harsh working conditions.
