TeSys D power contactor AC3 25A 3P 1NO 1NC 24VDC coil screw clamp terminals LC1D25BD

Power contactor for motor control and circuit protection. The TeSys D LC1D25BD contactor is a reliable device designed for controlling three-phase motors and protecting electrical circuits against overloads and short circuits. Designed by Schneider Electric, it combines compact dimensions with high performance, making it an ideal solution for both professional installers and end users. Its versatility allows it to be used in a wide range of industrial, building and HVAC applications.

Features and application

This 3-pole contactor with a rated current of 25A (AC-3) and a power of 11kW at 400V, is equipped with a 24V DC control coil and one normally open (1NO) and one normally closed (1NC) auxiliary contact. The screw terminal construction ensures easy and safe installation. This contactor is used in motor starters, lighting control systems, ventilation, air conditioning and other applications requiring frequent switching of the load. It can also be used in safety circuits thanks to the integrated auxiliary contacts.

Advantages and benefits

• High reliability: TeSys D contactors are characterized by high mechanical durability - up to 1.5 million switching cycles, which translates to a long service life and minimizes the risk of failure.
• Versatility: Thanks to the wide range of control voltages and rated powers, TeSys D contactors can be used in a variety of applications.
• Compact dimensions: It takes up little space in the control cabinet, which is particularly important in applications with limited space. The dimensions are 45 mm wide, 85 mm high and 101 mm deep.
• Easy installation: Screw terminals make it easy to connect wires, and the available technical documentation (including a digital version using a QR code) speeds up the installation process.
• Safety: Compliance with IEC60335-1 standard ensures increased resistance to fire and dust, which increases safety of use.
• Standard accessories: The ability to use the same additional accessories for contactors from 9A to 150A simplifies inventory management and reduces operating costs.
• High efficiency: The rated operating current for AC-1 at 400V is as high as 40A, and for AC-4 – 12A with a power of 5.5kW.
• Sustainable development: The product has a Green Premium label, which means compliance with the latest environmental regulations and a low carbon footprint throughout the product lifecycle.
