F204 AC-80/0.03

The ABB F204 AC‑80/0.03 is a 4‑pole residual current device rated 80 A and 30 mA leakage sensitivity, suitable for three‑phase AC electrical systems. It provides earth leakage (ground fault) protection by disconnecting circuits when leakage current exceeds the threshold, safeguarding people and electrical installations from shock and leakage faults. It’s designed for DIN‑rail installation and typical distribution board use.
