Why Choose the ABB RC-EH800/600 Surge Suppressor?

The ABB RC-EH800/600 Surge Suppressor (SK829007-D) is a genuine RC overvoltage suppression module designed to reduce voltage transients generated during contactor coil switching. Specifically developed for compatible ABB EH370 to EH800 and EK370 to EK1000 contactors, it protects control circuits and sensitive electronic equipment by minimising switching surges and electrical interference.

As an original ABB accessory, the RC-EH800/600 helps improve the reliability and longevity of industrial control systems by limiting voltage spikes that can occur when AC-operated contactor coils are de-energised. This contributes to smoother system operation while reducing stress on connected PLCs, relays and electronic control devices.

Designed for industrial motor control applications, the RC-EH800/600 installs directly onto the control terminals of compatible ABB contactors, providing a compact and dependable surge suppression solution for demanding environments.

Key Advantages

  • Genuine ABB RC surge suppressor.
  • Reduces switching overvoltage generated by AC contactor coils.
  • Helps protect PLCs, relays and electronic control equipment.
  • Designed for compatible ABB EH and EK series contactors.
  • Simple direct installation onto contactor control terminals.
  • Improves reliability of industrial control circuits.

Key Features

  • ABB RC-EH800/600 surge suppressor.
  • Manufacturer part number: SK829007-D.
  • RC suppression module for AC-operated contactor coils.
  • Suitable for 220 to 600 V AC control voltages.
  • Compatible with ABB EH370 to EH800 contactors.
  • Compatible with ABB EK370, EK550 and EK1000 contactors.
  • Compact plug-on accessory.
  • Original ABB low voltage accessory.

Reliable Protection Against Switching Surges

When an AC contactor coil is switched off, voltage transients can be generated that may interfere with nearby electronic equipment. The ABB RC-EH800/600 absorbs these transient voltages, helping to reduce electrical noise and improve the reliability of industrial control systems.

By limiting switching surges, the RC-EH800/600 helps protect sensitive control components while extending the operational life of industrial automation equipment. Its compact design and genuine ABB quality make it an ideal accessory for modern motor control installations.

Typical Applications

  • Motor control centres.
  • Industrial control panels.
  • PLC automation systems.
  • Industrial switchgear.
  • OEM machinery.
  • Power distribution and automation equipment.
