TeSys Deca power contactor, AC1, 20A 4P 2NO 2NC 48VAC coil screw terminals LC1D098E7

TeSys Deca Contactors – Reliable Control of Electrical Circuits

This four-pole power contactor from the TeSys Deca series, designed to operate at 48VAC, is a solid solution for both professional installers and end-users. Designed for use in AC-1 circuits, it is perfect for controlling non-inductive loads, ensuring safe and efficient operation of devices. Its construction based on screw terminals guarantees secure wire connections, minimizing the risk of errors during installation and operation.

The LC1D098E7 contactor is characterized by high mechanical endurance – it withstands as many as 15 million switching cycles at a frequency of 3600 cycles per hour. This translates to a long service life and minimal maintenance requirements, which is particularly important in demanding industrial applications. Built-in auxiliary contacts (2NO + 2NC) offer additional functionality, allowing easy creation of control and protection circuits. The mirrored arrangement of the NC contacts provides additional safety in safety circuits in accordance with the IEC standard.

Application and design features

This contactor finds wide application in various areas, from buildings and machines to water and sewage management and mining. Its compliance with many standards (IEC, UL, CSA, CCC, EAC, Marine) and Green Premium certification confirm its high quality and environmental care. Compact dimensions (85 mm height, 45 mm width and 92 mm depth) allow for easy mounting in tight spaces. The use of multi-standard screws facilitates installation, and the available online documentation using a QR code provides quick access to essential technical information.

It is worth noting the rated current Ie of 25A for AC-1 at 400V and the ability to operate at 440V AC (50/60Hz). Integrated auxiliary contacts adapted to signals with a minimum current of 1 mA allow direct connection to PLCs. In addition, the contactor is compliant with IEC 60335-1, which means it can be used in domestic installations and HVAC. Main contacts made of silver-nickel alloy ensure reliable current conduction for a long time of use.
