Suppressor Module · 50-129 VAC/DC · Varistor with LED Indicator · Schneider Electric LA4KE1FC
Varistor suppressor module for 50-129 VAC/DC control circuits on Schneider Electric TeSys K contactors and relays. Front clip-on module with LED indication to limit coil transient voltage and help protect adjacent control components in industrial and commercial panels.
What this product is for
The LA4KE1FC is a clip-on suppressor module for Schneider Electric TeSys K contactors and related control relays. It is used across 50-129 VAC/DC control circuits to limit transient voltage generated when the coil is switched.
Use for
Use for LC1K, LP1K, LP4K, CA2K, and CA3K series devices where coil surge suppression is required. Commonly used in industrial control panels, motor control assemblies, OEM equipment, and commercial electrical systems with sensitive control components nearby.
Avoid for
Avoid using this module on coils outside the 50-129 VAC/DC control voltage range or on incompatible contactor families. Do not treat it as a branch surge protective device for panelboard or service entrance protection.
Best for
Best for electricians and panel builders who need a simple front-mount coil suppression accessory for TeSys K devices. It is a practical choice where reducing switching transients can help limit nuisance effects on relays, PLC outputs, and other control wiring.
Installed in
Typically installed on the front side of compatible TeSys K contactors or relays using clip-on mounting with no tools required. Common installation locations include control cabinets, machinery panels, HVAC control sections, and packaged equipment.
Why this product exists
When a contactor or relay coil is de-energized, it can generate a transient voltage spike. This suppressor module uses varistor peak-limiting technology to reduce that spike and support cleaner control circuit operation. Typical guidance only: actual performance depends on coil type, wiring layout, installation conditions, and local electrical code.
Compared with similar products
Compared with a plain unsuppressed coil, this module adds transient limiting and a built-in LED indicator. Compared with other suppressor styles such as RC or diode modules, this version is a varistor type intended for 50-129 VAC/DC applications on compatible TeSys K devices.
