Suppressing diode, TeSys Deca, for LC1D09...D38 and LC1DT20...DT40 LAD4DDL

Suppression diode for TeSys Deca contactors – protection and reliability

This suppression diode, from the TeSys Deca series by Schneider Electric, is a key element ensuring reliable operation and protection of contactor control circuits. Designed to work with LC1D09…D38 and LC1DT20…DT40 models, as well as CAD control relays, it provides effective protection against transient overvoltages generated by coils.

Application and functionality

This diode protects the freewheeling diode in the control circuit, absorbing the energy generated when the contactor is switched off. This minimizes the risk of damage to installation components and extends their service life. This is particularly important in applications with inductive loads, where overvoltages are a common problem. The operating voltage in the range of 5-600 V DC makes the diode universal and can be used in a wide range of installations.

Mounting and compatibility

The diode is extremely easy to install using a snap-fit system. This does not affect the dimensions of the contactor – the whole remains compact and easy to integrate with existing systems. This is appreciated by installers for its speed and convenience, and by end-users for the lack of need to modify existing infrastructure.

Sustainable development and compliance with standards

The product meets the Green Premium requirements, which means compliance with RoHS and REACH directives. This guarantees that the component is environmentally friendly and does not contain harmful substances. This is important for both companies that care about sustainable development and end customers looking for ecological solutions.
