ABB 1SBN050020R1001 RV5/50 surge suppressor for 24–50 V AC/DC contactor coil protection in industrial control applications.
£48.76
The ABB 1SBN050020R1001 is a reliable surge suppressor accessory designed to protect ABB contactor coils from voltage spikes and switching transients. As part of the ABB RV5 surge suppressor series, this compact accessory improves contactor reliability by reducing electrical stress on control components in industrial switching applications.
This surge suppressor is designed for direct mounting on compatible ABB contactors, providing a simple and effective method of protecting electromagnetic coils against overvoltage events. Its compact design helps improve system durability while supporting reliable operation in industrial control environments.
With a 24–50 V AC/DC control voltage range, the ABB 1SBN050020R1001 is suitable for use with ABB N series contactors and contactor relays where coil protection and extended electrical service life are required. The device uses a varistor-based suppression method to limit transient overvoltages generated during coil switching.
Contactor coils generate transient voltage peaks when they are switched off. Surge suppressors help control these electrical disturbances, reducing stress on switching components and improving the reliability of industrial control systems.
The ABB RV5 series provides a practical solution for protecting contactors used in automation, motor control and electrical distribution applications. The 1SBN050020R1001 allows engineers to improve system performance while maintaining a compact and efficient control panel design.
