ABB SK829007-D RC-EH800/600 RC surge suppressor for 220-600 V AC contactor coils, designed to reduce overvoltage surge effects from coil operation.
£101.67
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.
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.
