TeSys D power contactor AC1 20A 4P 1NO 1NC 24VDC coil screw terminals LC1DT20BD

Power contactor – reliable load control

This four-pole TeSys D power contactor, designed to operate at AC1 20A, is a robust solution for controlling various loads. Equipped with one normally open (1NO) and one normally closed (1NC) auxiliary contact, it provides flexibility in control circuit design. Screw terminals facilitate quick and secure installation for both installers and end-users.

Construction and application

The LC1DT20BD contactor is designed for applications with non-inductive loads up to 20A/690V AC-1. Its compact dimensions (45 mm wide, 85 mm high, and 99 mm deep) allow for easy integration with existing installations. The 24V DC powered coil, equipped with a surge suppression module, guarantees stable operation even in harsh conditions. Built-in auxiliary contacts (1NO+1NC) in a mirrored configuration increase the functionality of the contactor, allowing direct use in safety circuits according to IEC standards.
