DESCRIBE

The ABB F4S 3200 4‑pole Air Circuit Breaker is a high‑current, low‑voltage protective device from ABB’s SACE F‑series (Megamax/Novomax class) designed for industrial and commercial three‑phase power distribution systems. It is rated at 3200 A continuous current and is built to handle heavy electrical loads with robust interruption performance. This breaker is used to protect electrical circuits against overloads, short‑circuits, and fault conditions, and can be installed in switchgear, distribution panels, and power distribution boards. Depending on configuration, the F4S frame can be fitted with an electronic trip unit (e.g., LSIG or PR1/P) to provide adjustable protective functions, status signaling, and optional communication/monitoring features. The 4‑pole design includes the neutral conductor for four‑wire systems.
