TeSys D power contactor AC3 25A 3P 1NO 1NC 220VDC coil screw terminals LC1D25MD

Power contactor – reliable motor control

This three-pole TeSys D power contactor with a rated current of 25A is designed for efficient motor control. It is suitable for both demanding industrial applications and building installations. The contactor's construction ensures high reliability and durability, and the ability to expand with additional accessories increases its functionality.

The contactor features screw connection of the main contacts, which simplifies installation and wiring. A 220V DC coil with a surge suppression module guarantees stable operation under various voltage conditions. Built-in auxiliary contacts (1NO+1NC) with a mirrored NC certificate allow direct use of the contactor in safety circuits, meeting the requirements of IEC standards.

Characteristics and application

The TeSys D contactor is a versatile device that finds application in a wide range of applications. The rated operating power for AC-3 at 400V is 11 kW, and for AC-4 also at 400V – 5.5 kW. The rated current for AC-1 at 400V is 40A, and for AC-4 – 12A. Thanks to this, the contactor is perfect for controlling various types of motors, ensuring their safe and efficient operation. Compact dimensions (85 mm height, 45 mm width and 101 mm depth) allow for easy installation in confined spaces. The possibility of mounting on a DIN rail or with screws further increases installation flexibility.

The device has numerous certificates (IEC, UL, CSA, CCC, EAC, Marine) and is Green Premium compliant (RoHS/REACh), confirming its high quality and care for the natural environment. The use of high-quality materials ensures a long service life of the device – mechanical endurance is as high as 15 million switching cycles at a frequency of up to 3600 cycles per hour.
