Schneider Electric LA4DA2U Contactor Suppressor Module

Product Description

The SCHNEIDER ELECTRIC LA4DA2U is a contactor suppressor module designed to reduce voltage transients and electromagnetic interference generated when a contactor coil is de-energized. Installed directly on compatible TeSys D series contactors, this accessory protects control circuits and sensitive downstream components from inductive switching spikes. It is a compact, plug-in style device that requires no additional tools to mount. Electricians and industrial maintenance technicians specify suppressor modules like this one to extend contactor coil life and improve overall panel reliability in motor control and power distribution applications.

This suppressor module is intended for use in industrial motor control centers, machine control panels, and commercial electrical distribution equipment. It mounts directly onto compatible Schneider Electric TeSys D series contactors rated in the LC1D and LP1D families. Typical installation scenarios include new panel builds and field retrofits where coil transient suppression is required to protect PLCs, relays, or other low-voltage control devices sharing the same circuit.

Key Features

• Plug-in accessory design mounts directly to compatible TeSys D series contactors without additional hardware
• Suppresses inductive voltage transients at the coil source to protect upstream control circuitry
• Compact form factor at 1.7 inches long, 2 inches wide, and 1.1 inches tall
• Lightweight construction at 0.05 pounds for minimal impact on panel load
• Direct OEM-style replacement for existing TeSys D contactor suppressor accessories

Compatibility

Designed for use with Schneider Electric LC1D400-D650, LC1D80-D150, LP1D400-D650, and TeSys D series contactors, as specified by the manufacturer.

Installation Notes

Installation is performed by a qualified electrician. De-energize and lock out the panel before installing or removing any contactor accessory. The module plugs directly into the designated accessory port on the contactor body — no additional wiring is required. Verify compatibility with the specific contactor model before installation and follow applicable NEC guidelines for industrial control panel work.
