TeSys D power contactor AC3 9A 3P 1NO 1NC 110VDC coil screw terminals LC1D09FD

TeSys D Power Contactor – Reliable Motor Control

This TeSys D series power contactor, designed for AC-3 circuits, provides reliable motor control up to 4 kW at 400 V. The construction based on proven Schneider Electric solutions guarantees high mechanical and electrical strength, which translates to long life and minimal downtime. The LC1D09FD contactor is an ideal solution for both industrial applications and public buildings where high reliability and safety are required.

Construction and Application

The LC1D09FD contactor is a three-pole device with a 110 V DC coil, designed for frequent switching of motor circuits. It has one normally open (NO) auxiliary contact and one normally closed (NC) auxiliary contact, enabling the implementation of various control and signaling functions. Screw terminals provide solid and reliable wire connections. The device is used to control pumps, fans, conveyors and other electrical equipment requiring frequent switching of the load.

Key Features and Benefits

• High Performance: Rated current of 9A for AC-3 allows control of motors up to 4 kW at 400V.

• Versatility: Rated operating power for AC-4 is 2.2 kW, which expands the range of applications for the contactor.

• Safety: It has built-in auxiliary contacts (1NO + 1NC) to facilitate the implementation of safety circuits.

• Durability: Mechanical endurance of 15 million switching cycles guarantees long device life.

• Easy Installation: Screw terminals provide quick and reliable wire connection.

• Wide Voltage Range: Coil powered by 110 V DC provides compatibility with various control systems.

• Compliance with Standards: Meets the requirements of IEC, UL and CSA standards, confirming its safety and reliability.

• AC-1 Rated Current: Up to 25A - allows use in lighting or heating circuits.

Technical Parameters in Practice

The rated operating current for AC-3 at 9A means that the contactor is adapted to frequent switching of induction motors with this rated current value. The rated power for AC-3 of 4 kW at 400 V allows control of most standard motors used in light industry and construction. The rated current value for AC-4 (6A) indicates the contactor's ability to work with loads of a variable nature, such as motors with brakes or fans with speed control. Internal impedance at 2.5 mOhm minimizes energy losses during current flow through the contactor.
