LAD4RCG Schneider Electric – TeSys Deca RC Suppressor Module for Contactor Coils, 50–127 V AC
The Schneider Electric LAD4RCG is a plug-in RC suppressor module for the coils of TeSys Deca contactors and control relays powered at 50–127 V AC, which includes the common 110, 115, 120 and 127 V AC control circuits. When a contactor coil is switched off, it generates a voltage spike that can disturb PLC outputs, interface relays and nearby electronics. The LAD4RCG absorbs that energy with an RC network, limiting the transient to a maximum of 3 Uc. This protects the control circuit and improves the reliability of the whole panel.

Compatible Devices
- 3-pole TeSys Deca contactors: LC1D09 to LC1D38
- 4-pole TeSys Deca contactors: LC1DT20 to LC1DT40 and LC1D098 to LC1D258
- TeSys Deca control relays: CAD32 and CAD50
The module clips onto the side of the device without changing the contactor’s overall dimensions, so it can be added to existing panels without re-spacing the DIN rail.
Why an RC Suppressor?
RC suppressors suit AC coils: they damp the switch-off surge without noticeably delaying the contactor’s opening. They are especially recommended when contactor coils are driven directly by PLC outputs, solid-state relays or electronic timers, or when wiring runs close to sensitive signal cables.
Operating Conditions
- Operating temperature: −25 to 55 °C
- Storage temperature: −40 to 80 °C
Standards and Certifications
The module complies with IEC/EN 60947-5-1, UL 60947-5-1, CSA C22.2 No 60947-5-1 and GB/T 14048.5, and is UL and CSA certified. It is a Schneider Electric Green Premium product, RoHS and REACH compliant.
Choose the Right LAD4 Module for Your Coil Voltage
Always select the suppressor that matches the coil’s control voltage. The LAD4RCG covers 50–127 V AC coils. Other LAD4 suppressor modules cover lower or higher AC voltages and DC coils.
