The ABB F2S 2500 A 4‑pole WMP Air Circuit Breaker is a high‑current low‑voltage protective device designed for three‑phase power distribution systems in industrial and commercial electrical installations. It belongs to ABB’s range of withdrawable (WMP) air circuit breakers, providing reliable protection and switching of electrical circuits carrying up to 2500 A of continuous current. The breaker interrupts fault currents and protects against overloads, short circuits and abnormal conditions when equipped with a suitable electronic trip unit. The WMP (withdrawable movable part) design allows the breaker to be safely inserted and removed from its switchgear frame for maintenance or inspection without disconnecting the main busbars, improving safety and uptime.

The ABB MM21 MM 21 is an advanced industrial control module designed for precision and reliability in automation systems. It efficiently manages complex operations in manufacturing and processing industries.
