TeSys K power contactor AC3 9A 3P 1NO 24VAC coil screw clamp terminals LC1K0910B7

Power contactor for controlling motors and loads

This three-pole TeSys K power contactor is a reliable solution for controlling motors and non-inductive loads. Designed for standard applications, it offers high performance and durability. It is ideal for both industrial and commercial installations where compactness and reliability are required.

The LC1K0910B7 contactor allows effective control of motors up to 4 kW at 400 V (AC-3) and non-inductive loads up to 20 A at 400 V (AC-1). Its design with a built-in 1NO auxiliary contact simplifies integration with existing control systems. Screw terminals provide solid and secure wire connections.

Characteristics and application

The TeSys K contactor is characterized by its compact dimensions (45 mm wide), which allows mounting in limited space, both on a DIN rail and by means of screws. It is adapted for frequent operations – withstands up to 600 cycles/hour – and also for operation in an environment with a temperature of up to 50°C. Thanks to compliance with many standards (IEC, UL, CSA, CCC, EAC) and the Green Premium certificate (RoHS/REACh), the product meets stringent safety and environmental requirements.

The application of the contactor includes:

• Control of electric motors in various industrial applications.
• Switching on and off non-inductive loads, such as heaters or lighting.
• Construction of motor starting circuits.
• Automation of production processes.
• Building and commercial installations requiring reliable load control.
