Super-immunised RCDs for sensitive loads

Super-immunised RCDs are designed for installations where electronic equipment can generate disturbances, harmonics or transient leakage currents. Their Class A+SI technology helps avoid unwanted trips while maintaining residual current protection.

They are recommended in circuits with LED drivers, variable frequency drives, IT equipment, power supplies and other sensitive loads.

  • Immunity: reduces nuisance tripping caused by disturbances.
  • Class: Class A+SI response for modern electronic loads.
  • Sensitivity: 30mA and 300mA options according to the installation.
  • Use: LED lighting, drives, IT and sensitive equipment.

This category is focused on continuity of service in disturbed circuits and must not duplicate generic RCD content.
