Power contactor, TeSys Deca, I=18A [AC-3], 42VAC coil, 50Hz, 1NO 1NC auxiliary contact, screw terminals LC1D18D5

TeSys Deca LC1D18D5 power contactor is a reliable solution for controlling loads in a wide range of industrial and building applications. Designed for easy installation and high performance, this 3-pole contactor (1NO+1NC) provides effective protection and control for motors and other electrical devices.

Its compact design with dimensions of 45 x 77 x 86 mm allows for mounting on a DIN rail or screw mounting, simplifying integration with existing installations. The contactor is designed to work with non-inductive loads up to 18A/690V AC-3, and its rated power for AC-3 at 400V is 7.5 kW. Additionally, it has built-in auxiliary contacts (1NO+1NC) in a mirror configuration, which increases its functionality and safety.

Powered by a 42V AC 50Hz coil, the contactor offers a wide range of operating voltages for AC – from 440V to 440V (50Hz and 60Hz). Made of high-quality materials, including main contacts made of silver-nickel alloy (LC1D09-LC1D18) or silver-tin oxide (LC1D25 and higher), it guarantees long-lasting and reliable operation even in harsh conditions.

This model is characterized by high mechanical endurance – up to 15 million switching cycles and the ability to perform up to 3600 cycles per hour. Compliance with IEC 60335-1 ensures increased resistance to fire and dust, making it an ideal choice for applications in residential buildings, heating, ventilation and air conditioning (HVAC) systems, and industry.

Additional advantages include:

• Easy installation thanks to multi-standard screws.
• Integrated auxiliary contacts in a mirror standard (NO+NC), allowing direct use in safety circuits in accordance with IEC.
• Simple selection thanks to the catalog number including the rated current in AC-3 category.
• Access to technical documentation online using a QR code.
• A wide range of accessories allowing the contactor to be adapted to specific application requirements.
• Green Premium compliance – ensuring compliance with environmental protection regulations (RoHS/REACh) and transparency of information about environmental impact.

The TeSys Deca LC1D18D5 contactor is not only a reliable control device, but also an element of sustainable development, meeting the highest standards of ecology and safety.
