TeSys D power contactor 50A 3P 1NO 1NC 24VAC coil EVK screw terminals LC1D50AB7

Power contactor for demanding applications

This three-pole TeSys D power contactor with a rated current of 50A is designed for reliable control of electric motors. Equipped with one normally open (1NO) and one normally closed (1NC) auxiliary contact, it provides flexibility in control circuit design. The 24VAC coil voltage makes it compatible with a wide range of control systems. This contactor is a solid solution for both professional installers and end-users looking for reliability and durability.

Characteristics and application

The LC1D50AB7 contactor finds application in various industrial applications, commercial buildings and power supply systems. Thanks to its high mechanical endurance (up to 15 million switching cycles) and the ability to perform up to 3600 cycles per hour, it is ideal for applications requiring frequent switching. Compliance with IEC, UL, CSA, CCC, EAC and Marine standards guarantees safety and versatility. EverLink BTR screw terminals provide secure and durable electrical connections.

Advantages and benefits

• High performance: The rated operating power for AC-3 is as high as 22 kW at 400V, and the rated operating current Ie is 50A.
• Versatility: It has both main contacts (3NO) and auxiliary contacts (1NO+1NC), which facilitates integration with various control systems.
• Durability: Mechanical endurance at the level of 15 million switching cycles guarantees long device life even in intensive working conditions.
