For motor-control work, AC-3 and AC-4 are not interchangeable labels. Official manufacturer documentation describes AC-3 around normal squirrel-cage motor starting and switching off during running, while AC-4 covers more severe operations such as plugging, inching or reversing. Record the actual operating sequence, then use the exact manufacturer’s rating table for that duty.<\/p>\n\n\n\n
