ABB 1SBN050010R1000 RV5/50 24-50V AC/DC Clip-On Surge Suppressor Accessory for Low-Voltage Switch Technology

The ABB RV5/50 (SKU: 1SBN050010R1000) is a clip-on surge suppressor accessory designed for low-voltage switch technology, rated for 24–50 V AC (50/60 Hz) or 24–50 V DC. Engineered to protect contactors and control relays from voltage transients and switching surges, the RV5/50 snaps directly onto compatible ABB devices without additional wiring tools. Its compact footprint — 30.25 mm × 10.5 mm × 32.4 mm and only 15 g — makes it ideal for space-constrained control panel installations.
