The ABB RV‑BC6/250 is a varistor‑type surge suppressor designed for use with miniature contactor coils and control circuits. It helps protect electrical components—especially DC contactor coils—by limiting voltage spikes and overvoltage peaks that occur when coils are switched off. Its compact design with screw or cable‑lug terminals makes it easy to install onto compatible ABB contactors, reducing electrical noise and extending the life of the control system.
