TeSys D power contactor AC3 9A 3P 1NO 1NC 48VAC coil screw terminals LC1D09E7

TeSys D power contactor – reliable motor control

This 3-pole TeSys D power contactor is designed for efficient motor control. The rated operational power for AC-3 is 4 kW at 400 V, and the rated operational current Ie is 9 A. This makes it suitable for a variety of industrial and construction applications. The contactor is designed for frequent switching, withstanding up to 3600 cycles per hour, guaranteeing long-lasting and reliable operation even in demanding conditions.

The contactor's construction is based on solid screw terminals, providing secure and safe connections. Built-in auxiliary contacts – 1NO + 1NC – with a mirrored NC certificate increase the device's functionality and allow direct use in safety circuits in accordance with IEC standards. Compact dimensions (45 mm wide, 77 mm high and 86 mm deep) allow for easy mounting on DIN rails or with screws.

Application and benefits

The TeSys D contactor is a versatile solution for installers and end-users. Its compliance with many standards (IEC, UL, CSA, CCC, EAC, Marine) and Green Premium certification (RoHS/REACh) confirm its high quality and environmental care.

• Versatility: Suitable for controlling motors in industrial plants, buildings, power systems and wastewater management.
• Safety: Integrated auxiliary contacts with a mirrored NC certificate allow the construction of safe control circuits.
• Durability: Mechanical endurance of 15 million switching cycles ensures long device life.
• Easy installation: Screw connections facilitate mounting and wiring.
• Sustainable development: Green Premium certification guarantees compliance with environmental regulations.
• Wide voltage range: Designed to operate at a control voltage of AC 48V (50/60Hz).
• High efficiency: Rated operating current for AC-1 is as high as 25A, and for AC-4 – 6A.

Technical characteristics in practice

The LC1D09E7 contactor is characterized by high reliability thanks to the use of high-quality materials and precise construction. Category C characteristics allow it to react more slowly to short current surges, so it tolerates starting devices with a motor well. The rated operational power for AC-4 is 2.2 kW, which means that this contactor will work in applications requiring frequent load changes. It protects the circuit against overload and short circuit — like most circuit breakers in this class. Additionally, technical documentation is available online using a QR code, making it easier to select the appropriate parameters and solve any problems during installation or operation of the device.
