Schneider Electric LAD4V3U Contactor Suppressor Module

Product Description

The SCHNEIDER ELECTRIC LAD4V3U is a suppressor module designed as an accessory for contactors in the TeSys D series. It mounts directly to compatible contactor bodies to suppress voltage transients and electromagnetic interference generated when the contactor coil is de-energized. This type of suppression protects sensitive control circuitry and extends the service life of the contactor and surrounding components. The LAD4V3U measures 1.5 inches in length, 0.4 inches in width, and 0.3 inches in height, making it a compact add-on that integrates without adding significant bulk to the assembly. Licensed electricians and industrial controls technicians are the primary installers.

This suppressor module is intended for use in industrial and commercial control panel applications where TeSys D series contactors are installed. It is commonly used in motor control centers, machine control panels, and distribution boards where contactor switching occurs frequently and transient suppression is required to protect downstream control components. Compatible units include the LC1D40A through D65A and LC1DT60A through DT80A contactor families within the TeSys D lineup.
