TeSys K power contactor AC3 12A 3P 1NO 24VAC coil screw terminals LC1K1210B5

Power contactor for controlling motors and loads

This three-pole TeSys K power contactor, designed to operate at 24VAC, is a reliable solution for controlling motors up to 5.5kW (AC-3, 400V) and non-inductive loads up to 20A (AC-1, 400V). Its compact design (dimensions 45x57x58mm) and the possibility of mounting on a DIN rail or with screws, facilitate installation in switchboards and control cabinets. This contactor is ideal for both professional installers and end-users looking for a solid and efficient component for automation systems.

Design and application

The LC1K1210B5 contactor has three normally open main contacts (3NO) and one normally open auxiliary contact (1NO), allowing for flexible control circuit configuration. Screw terminals ensure secure and durable wire connections. The device is adapted for frequent switching – up to 600 cycles per hour – and operation in ambient temperatures up to 50°C. This makes it suitable for demanding industrial and commercial conditions. It can be used in applications such as:

• Control of electric motors in industry
• Building automation
• HVAC systems (heating, ventilation, air conditioning)
• Lighting control
• Applications requiring frequent switching of loads

Advantages and product features

• High efficiency: Rated operating current for AC-3 is 12A at 400V, ensuring reliable operation even under heavy loads.
• Versatility: Suitable for controlling both AC-3 motors and AC-1 non-inductive loads.
• Compact dimensions: Allow for mounting in limited space.
• Easy installation: Possibility of mounting on a DIN rail or with screws facilitates installation.
• Safety and compliance with standards: It has IEC, UL, CSA, CCC and EAC certificates, and is also compliant with RoHS and REACH (Green Premium) directives. This guarantees safety of use and care for the natural environment.
• Durability: Adapted to work in harsh industrial conditions (up to 600 cycles/hour, ambient temperature up to 50°C).
• Modular design: Allows for easy expansion of the control system.
