Rated 20A with 3P, the Schneider A9F74320 belongs to the Acti9 iC60N family of modular circuit breakers, one of the most common breaker ranges in industrial and building panels.
Acti9 breakers clip onto a 35 mm DIN rail, can be fed with comb busbars from the top or bottom, and show the contact position on the toggle, so a tripped circuit is easy to find during maintenance.
