TeSys D power contactor AC3 115A 3P 1NO 1NC 48VAC coil LC1D115E7

TeSys D power contactor – reliable motor control

This three-pole TeSys D power contactor with a rated current of 115A in AC-3 category is a robust solution for controlling motors up to 55 kW at 400V. Equipped with a 48VAC powered coil, it provides reliable switching of the load. The contactor design is intended for long-term operation, withstanding up to 15 million switching cycles and 3600 cycles per hour.

Design and application

The LC1D115E7 contactor is characterized by its compact dimensions (120 mm wide, 158 mm high, and 136 mm deep) and the possibility of mounting both on DIN rails and direct screwing. It has built-in auxiliary contacts – one normally open (1NO) and one normally closed (1NC) – which simplifies the construction of control and safety circuits. Connection of power cables is done using screw connections, and control – also using screw terminals. This solution is particularly appreciated by installers due to its ease and speed of installation.
