TeSys D power contactor AC3 25A 3P 1NO 1NC 110VDC coil screw terminals LC1D25FD

Power contactor for controlling motors and more

This three-pole power contactor from the TeSys D series, with a rated current of 25A, is a reliable solution for controlling AC-3 motors up to 11kW at 400V. It is suitable for both industrial and building applications, providing effective and safe circuit switching. A 110V DC coil ensures compatibility with various control systems.

Design and application

The LC1D25FD contactor features a compact design (45x85x101 mm) and can be mounted on a DIN rail or directly on a plate. Equipped with three main NO contacts and one auxiliary NO and NC contact, it allows for flexible configuration of control circuits. Screw terminals ensure secure and durable wire connections. This device is ideal for:

• Controlling electric motors in various industrial applications.
• Applications in buildings – heating, ventilation and air conditioning (HVAC) systems.
• Solutions requiring frequent circuit switching.
• Safety applications thanks to mirrored auxiliary contacts (NO+NC).

Advantages and characteristic features

• High reliability: Designed for operation with a frequency of up to 3600 cycles per hour at an ambient temperature of up to 60°C.
• Versatility: Compliance with many standards (IEC, UL, CSA, CCC, EAC, Marine) ensures the possibility of use in various countries and industries.
• Safety: Built-in NO+NC auxiliary contacts facilitate the implementation of safety circuits in accordance with IEC standards.
• Durability: Made of high-quality materials guarantees a long service life – mechanical endurance is as many as 15 million switching cycles.
• Easy installation: Compact dimensions and the possibility of mounting on a DIN rail facilitate installation.
• Sustainable development: The product meets Green Premium requirements (RoHS/REACh), which means compliance with environmental protection regulations.
• Wide range of applications: Suitable for operation in harsh environmental conditions due to high resistance to dust and fire (compliance with IEC60335-1).
• Efficiency: Rated operating power for AC-4 is 5.5 kW at 12A, making it suitable for applications requiring frequent motor starts and stops.

Additionally, the contactor has an integrated surge-limiting diode, which increases its resistance to interference and extends its service life. Technical documentation is available online using the QR code on the product.
