Square D LAD4RC3U-1PC RC Suppressor Module for TeSys Contactors

The Square D LAD4RC3U-1PC is an RC suppressor module designed for use with TeSys contactors. This protection module suppresses voltage spikes generated during the switching of inductive loads, extending the life of contactor contacts and protecting connected equipment from transient overvoltages.

Key Features:

• RC (resistor-capacitor) circuit design for effective voltage spike suppression
• Compatible with TeSys LC1D09 through LC1D38 contactor series
• Snap-on mounting for quick and easy installation on contactor terminals
• Rated for use with 24-250V AC/DC control circuits
• Compact design maintains minimal panel space requirements
• UL listed and IEC compliant for industrial control applications

The LAD4RC3U suppressor module is particularly effective when switching motor loads, solenoids, transformers, and other inductive devices that generate high voltage transients during de-energization. Installation requires no additional wiring—the module simply clips onto the contactor coil terminals.
