TeSys D power contactor 40A 3P 1NO 1NC 400VAC coil, EVK screw terminals LC1D40AV7

TeSys D contactors – reliable motor control

The TeSys D power contactor is a component designed to control electric motors, providing reliable switching on and off of circuits. Model LC1D40AV7, with a rated current of 40A, is a universal solution for both installers and end users. The contactor's construction is based on proven technology, guaranteeing long life and high resistance to working conditions.

Construction and application

This contactor is three-pole (3P) with one normally open (1NO) and one normally closed (1NC) auxiliary contact. It is designed to operate with a control voltage of AC 400V. EVK (EverLink) screw terminals provide secure and quick connection of wires. The width of the contactor is 55mm, allowing for mounting in tight spaces. It finds application in controlling motors in buildings, industrial plants and power supply systems. Thanks to its high mechanical strength (up to 15 million switching cycles) it is ideal for applications requiring frequent switching.
