Limiter module, diodes 12x24V AC/DC LA4KC1B

Surge Limiter Module – Protection and Signaling in Control Circuits

This module, designed to work with TeSys K contactors (LP.K, CA3K, CA4K), provides effective protection against overvoltages in 12-24V DC control circuits. Its function is to suppress disturbances occurring during switching, which translates to reliable operation and longer life of connected devices. The built-in diode protects against the effects of reverse overvoltages, and the presence of an LED indicator informs about correct power supply.

Functionality and Application

The LA4KC1B module is a component dedicated to both professional installers and end-users looking for a reliable solution in the field of electrical installation protection. Installation is done by snapping onto the front of the contactor – it is quick, intuitive and does not require tools. The element's polarity is clearly marked, minimizing the risk of incorrect connection. Thanks to its compact size, the module does not disrupt the aesthetics of the installation.
