TeSys K power contactor AC3 12A 3P 1NO 220/230VAC coil screw terminals LC1K1210M7

Power contactor – reliable control of motors and loads

This TeSys K power contactor is a key element in control systems, designed for reliable operation with motors and various types of loads. Designed for AC3 applications with a current of 12A, and AC1 with a current of 20A, it is a versatile solution for both professionals and end users. The compact design and high-quality workmanship guarantee long-lasting and efficient operation in demanding conditions.

Characteristics and application

This contactor is three-pole (3P) with one normally open auxiliary contact (1NO), providing flexibility in control circuit configuration. A 220/230VAC coil allows for easy integration with existing electrical installations. Screw terminals ensure secure and durable wire connections. It can be used in a wide range of applications, from simple motor control circuits to more complex industrial automation systems. The rated power for AC-3 at 400V is 5.5kW, and for AC-4 – 2.2kW, making it suitable for controlling various devices.

Advantages and benefits

• Compact dimensions: Width of 45mm allows for mounting in tight spaces, optimizing the use of space in control cabinets.
• High reliability: Construction based on proven Schneider Electric technologies ensures long-lasting and trouble-free operation.
• Versatility: Can be used in both AC-3 (motor control) and AC-1 (non-inductive load control) applications.
• Easy installation: Screw terminals facilitate wire connection, reducing installation time.
• Safety: Compliance with many standards (IEC, UL, CSA, CCC, EAC) guarantees safety of use and compliance with regulations.
• Efficiency: Rated operating current Ie for AC-3 at 400V is 12A, and for AC-1 – 20A, allowing for efficient control of loads with different power.
• Durability: Designed for frequent switching – up to 600 cycles/hour – and operation at temperatures up to 50°C.
• Sustainable development: The product meets Green Premium standards (RoHS/REACh), which means compliance with environmental protection regulations.

Technical parameters in practice

The rated operating current for AC-4 at 400V is 6A – this is important when controlling motors with high starting torque. The C characteristic allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well. The rated control voltage Us at 220…230V ensures compatibility with most standard electrical installations in Poland. The rated power for AC-3 at 400V of 5.5kW indicates its capabilities in controlling medium-power motors.
