TeSys K power contactor AC3 9A 3P 1NC 24VAC coil screw terminals LC1K0901B7

Compact TeSys K contactor for motor and load control

The TeSys K power contactor is a reliable solution for controlling AC3 motors up to 9A (at 690V) and non-inductive loads up to 20A (at 400V). Its miniature dimensions – only 45 mm wide – allow for easy installation even in crowded control cabinets. The device is controlled by 24V AC voltage and equipped with one normally open auxiliary contact (1NC), which increases its functionality.

Application and design features

This three-pole contactor (3NO) finds application in a wide range of applications, from simple motor control circuits to more complex automation systems. Its solid construction ensures durability and reliability, confirmed by numerous certificates (IEC, UL, CSA, CCC, EAC). The use of screw terminals facilitates wire connection, and the possibility of mounting on a DIN rail or by screws provides installation flexibility. The contactor is designed to operate at temperatures from -40°C to 50°C and withstands up to 3600 operating cycles per hour.

Operating parameters and user benefits

The rated power of the contactor is 4 kW at 400V AC (AC-3) and 2.2 kW at 400V AC (AC-4). The rated operating current is 9A for AC-3 and 20A for AC-1 at 400V. Thanks to the C characteristic of the coil, the contactor copes well with starting devices with a motor, reacting more slowly to short current surges. Compact size and high reliability make it an ideal choice for both professional installers and end-users looking for an effective solution for controlling electrical loads. Additionally, compliance with the Green Premium standard guarantees compliance with environmental protection requirements.
