TeSys K power contactor AC3 12A 3P 1NO 230VAC coil screw terminals LC1K1210P7

TeSys K LC1K1210P7 power contactor from Schneider Electric is a reliable solution for motor control. Its compact dimensions (45 x 58 x 57 mm) allow for easy integration even in limited spaces, and its parameters make it suitable for both professional installers and end-users.

Characteristics and application

This 3-pole contactor with a 230VAC coil and screw terminals is designed for frequent switching of electrical circuits. The rated operating power for AC-3 is 5.5 kW at 400V, and the rated current is 12A. This makes it ideal for applications requiring control of medium-power motors, such as pumps, fans, or conveyors. It has one normally open auxiliary contact (1NO), which can be used to signal the contactor status or to control other elements of the circuit.

Advantages and benefits

• Compact size: Allows mounting in tight control cabinets and switchboards – this is especially important when modernizing existing installations.
• High efficiency: Rated current of 12A (AC-3) at 400V ensures reliable operation even with loads requiring higher starting current. C characteristic allows it to react slower to short current surges, therefore it tolerates starting devices with a motor well.
• Versatility: Suitable for a wide range of motor applications, from simple home applications to more demanding industrial installations.
• Safety: Protects the circuit from overload and short circuit — like most circuit breakers in this class.
• Durability: Made of high-quality materials, which guarantees long life and reliable operation.
• Comparable performance to EATON DILM series: Offers a similar number of switching cycles (1.2 million), making it an attractive alternative to solutions from other manufacturers.

Additionally, this contactor is characterized by a rated operating current for AC-1 of 20A and the ability to operate at 440V (AC 50/60Hz). The rated operating power for AC-4 is 2.2 kW at 400V and a rated current of 6A. The type of connection for the main contacts is screw connection, which ensures a secure and durable connection of the wires.
