TeSys Deca power contactor, AC1, 25A 4P 2NO 2NC 110VAC coil screw terminals LC1D128F7

Power contactor for demanding applications

This four-pole power contactor from the TeSys Deca series, catalog number LC1D128F7, is a reliable solution for controlling loads in industrial and building installations. Designed to operate at 110VAC, it offers high performance and durability, and its compact dimensions (85 mm high, 45 mm wide and 92 mm deep) make it easy to install in confined spaces. This contactor is particularly well suited for use with resistive loads, but will also perform well in other applications.

Construction and application

The LC1D128F7 contactor has a 2NO+2NC (two normally open and two normally closed) contact configuration and additional auxiliary contacts 1NO+1NC, providing flexibility in control circuit design. The rated operating current for AC-3 is 12A at 400V, and for AC-1 – 25A. It can be used in circuits with a voltage of up to 690VAC. Connection is made using screw terminals, ensuring a secure and durable connection of the wires. The wide range of applications includes industrial plants, commercial buildings and HVAC systems.
