TeSys D power contactor AC3 12A 3P 1NO 1NC 24VDC coil LC1D123BD

Power contactor for controlling motors and resistive loads

The TeSys D LC1D12BD contactor is a reliable component used to control motors and resistive loads. Designed to operate in AC-1, AC-3 and AC-4 categories, it provides versatile application in industrial installations and HVAC systems. The contactor's construction with three poles (3NO) and built-in auxiliary contacts (1NO + 1NC) allows for efficient management of electrical circuits. A 24V DC coil with overvoltage module guarantees stable operation and increases installation safety.

Construction and characteristic features

The LC1D12BD contactor is characterized by a compact design (99 mm high, 45 mm wide and 95 mm deep) and the possibility of mounting on a DIN rail or with screws. Spring-loaded terminals facilitate and speed up the connection of wires, minimizing installation time. High mechanical endurance (30 million cycles) and electrical endurance (2 million cycles at 12A AC-3) ensure long-lasting and trouble-free operation even in demanding conditions. In addition, the contactor meets a number of safety standards (IEC, UL, CSA, CCC, EAC, Marine), which confirms its high quality and compliance with applicable standards.

Technical parameters and application

This contactor is adapted to operate at a rated operating current of 12A for AC-3 at 400V, allowing control of motors up to 5.5 kW. The rated operating power for AC-4 at 400V is 3.7 kW. The rated current for AC-1 at 400V is 25A. The contactor also has integrated auxiliary contacts in a mirror configuration (NO+NC), which allows direct use in safety circuits in accordance with IEC standards. This makes it an ideal solution for both professional installers and end-users looking for a reliable and versatile device for controlling motors and other electrical loads. Compliance with IEC60335-1 ensures increased resistance to fire and dust, making it suitable for use in various industrial environments.
