TeSys Deca power contactor, AC1, 20A 4P 2NO 2NC 24VAC coil screw terminals LC1D098B7

TeSys Deca Power Contactor – reliable circuit control

The TeSys Deca LC1D098B7 contactor is a four-pole device (2NO+2NC) designed for reliable control of electrical circuits, especially in applications with non-inductive loads. Designed to operate with a current of 20A at a voltage of 690V AC-1, it is a solid element of electrical installation both in professional and home applications. A 24VAC coil ensures compatibility with a wide range of control systems.

Construction and functionality

The contactor is characterized by a compact design with dimensions of 85 mm (height), 45 mm (width) and 92 mm (depth), which facilitates mounting in limited spaces. Connection of wires is done using screw terminals, providing a secure and durable connection. Built-in auxiliary contacts (1NO+1NC) with a mirrored NC certificate allow direct use of the contactor in safety circuits, meeting the requirements of the IEC standard. Auxiliary contacts are adapted to work with signals with a minimum current of 1 mA, which allows them to be connected directly to PLCs.

Applications and advantages

This contactor is ideal for applications in buildings, industrial plants, heating, ventilation and air conditioning systems, and many other applications requiring reliable control of electrical circuits. Its mechanical endurance of 15 million switching cycles and the ability to operate at a frequency of up to 3600 cycles per hour guarantee long-lasting and trouble-free operation. Compliance with IEC 60335-1 ensures increased resistance to fire and dust, which increases safety. Additionally, the product has certificates of many standards (IEC, UL, CSA, CCC, EAC, Marine) and meets the requirements of Green Premium (RoHS/REACh), which confirms its compliance with environmental protection regulations.
