Schneider Electric LA4SKE1U Contactor Suppressor Module

Product Description

The SCHNEIDER ELECTRIC LA4SKE1U is a suppressor module designed as an accessory for TeSys SK series contactors and control relays. Suppressor modules reduce voltage transients and electromagnetic interference generated when a contactor coil de-energizes, protecting sensitive control circuits and extending the service life of connected equipment. This module mounts directly to compatible contactors in the TeSys SK family and is installed by licensed electricians during panel assembly, machine wiring, or contactor replacement work.

This suppressor module is intended for use in low-voltage control panels, motor control centers, and industrial automation enclosures where TeSys SK contactors and relays are employed. Its compact form factor suits space-constrained installations. Typical applications include motor starter circuits, control relay assemblies, and automation panel builds in commercial and light industrial settings.

Key Features

• Suppresses coil voltage transients to protect downstream control circuits
• Direct-mount accessory — attaches to compatible TeSys SK contactors and relays without additional hardware
• Compact dimensions: 1 inch length, 0.6 inches width, 0.3 inches height
• Lightweight at 0.01 pounds, adding negligible load to the contactor assembly
• UNSPSC Code 39121529 for procurement and catalog classification

Compatibility

Designed for use with the following SCHNEIDER ELECTRIC TeSys SK series devices: CA2SK, CA3SK, LC1SK06, LC1SKGC, LP1SK06, and TeSys SK contactors.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out the panel before installing or removing the suppressor module. The module clips directly onto the contactor coil terminals — verify orientation matches the contactor's accessory mounting interface before seating. Do not install on contactors outside the specified compatible series, as mismatched accessories may not seat securely or may not provide proper suppression.
