TeSys D power contactor AC3 12A 3P 1NO 1NC 24VDC coil LC1D12BD

Motor control power contactor

This 3-pole TeSys D contactor from Schneider Electric is designed for reliable motor control. A rated current of 12A in AC-3 category at 400V and a power of 5.5kW make it a robust solution for various industrial applications and HVAC installations. Equipped with a 24V DC coil and 1NO and 1NC auxiliary contacts, it offers flexibility in configuration and integration with control systems.

Design and operating parameters

The LC1D12BD contactor is characterized by its compact dimensions – 45 mm wide, 77 mm high and 86 mm deep – making it easy to mount even in limited spaces. The connection of the main contacts is made using screw connections, ensuring secure and durable electrical connections. The rated current for AC-1 at 400V is 25A, and for AC-4 – 7.5A with a power of 3kW. The use of characteristic C allows for trouble-free starting of devices with a motor, reacting more slowly to short current surges.

Durability and reliability

TeSys Deca contactors are distinguished by their high mechanical durability – as many as 15 million switching cycles, which translates into a long service life and minimizes the risk of failure. Built-in auxiliary contacts (1NO + 1NC) in a standard mirror arrangement allow direct use of the contactor in safety circuits in accordance with the IEC standard. In addition, the auxiliary contacts are adapted to signals with a minimum current of 1 mA, ensuring compatibility with PLCs. It is worth noting that TeSys D contactors have a certificate of compliance with IEC60335-1, which confirms their increased resistance to fire and dust.
