TeSys K power contactor AC3 12A 3P 1NO 24VAC coil screw terminals LC1K1210B7

Power contactor for controlling motors and loads

This TeSys K power contactor from Schneider Electric is a reliable solution for controlling motors and resistive loads. Designed for performance and durability, it performs well in both professional and home installations. The compact design (45 mm wide) makes it easy to install, and its versatility allows it to be used in various configurations.

Characteristics and application

This contactor is three-pole (3P) and designed to operate at AC 400 V, offering a rated power of 5.5 kW for AC-3 loads (motors) and 20 A for AC-1 loads (resistive). It has one normally open auxiliary contact (1NO), which can be used to indicate the status of the contactor or to control other elements of the circuit. The rated operating current is 12 A for AC-3 and 20 A for AC-1. The coil is powered by 24 VAC, making it ideal for use with popular control systems. Thanks to this, this contactor finds application in a wide range of applications – from simple home installations to advanced industrial systems.

Advantages and benefits

• Compact size: Allows installation in tight spaces, optimizing the use of space in control cabinets.
• High reliability: Ensures long-lasting and trouble-free operation, minimizing the risk of downtime and repair costs.
• Versatility: Suitable for controlling both motors and resistive loads, increasing installation flexibility.
• Easy installation: Connection via screw terminals is simple and intuitive, reducing installation time.
• Compliance with standards: Meets the requirements of many standards (IEC, UL, CSA, CCC, EAC), guaranteeing safety and compliance with regulations.
• Energy efficiency: Low coil power consumption helps reduce operating costs.
• Mechanical durability: Designed for a large number of operating cycles (up to 600 cycles/hour), ensuring a long service life.
• Safety: Provides effective protection of the circuit against overload and short circuit - like most circuit breakers in this class.

Thanks to this, the TeSys K contactor is not only a control element, but an investment in the reliability and efficiency of your electrical installation. Category C characteristics allow it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.
