ABB SK829007-A RC-EH300/48 24-48 V AC RC surge suppressor designed to reduce overvoltage surge effects from contactor coil operation in low-voltage control circuits.
£46.46
The ABB SK829007-A is a compact and reliable RC surge suppressor designed to reduce overvoltage surge effects caused by contactor coil operation. Identified as RC-EH300/48, this ABB accessory is suitable for use with selected ABB block contactors and helps improve the reliability of low-voltage control circuits.
This surge suppressor is designed for use in industrial control panels, motor control systems and automation equipment where contactor coil switching can generate transient voltage spikes. By suppressing these surges, the SK829007-A helps protect surrounding control components, reduce electrical interference and support stable operation of connected equipment.
With a rated operating range of 24–48 V AC, the ABB RC-EH300/48 is suitable for low-voltage AC coil applications. Its compact design and straightforward fitting make it a practical accessory for panel builders, maintenance engineers and electrical contractors working with ABB contactors and controlgear.
Contactor coils can generate voltage transients when energised or de-energised. Surge suppressors such as the ABB SK829007-A help limit these transient effects, supporting improved reliability for relays, PLC inputs, control electronics and other components within the same electrical panel.
The ABB RC-EH300/48 is designed for industrial environments where stable switching performance and reduced electrical noise are important. It is a practical accessory for motor control centres, machine panels and automation systems using compatible ABB contactors.
