It carries a 27 A rated operational current at 480 V and a 5 hp rating at 230 V, which tells you it can handle a 5 hp motor on a 230 V single-phase or three-phase line, or a 27 A resistive load at 480 V.
Switching frequency and thermal limits
Rated for up to 1 000 operations per hour in AC-1 resistive duty, and 750 ops/h in AC-3 motor switching. That's enough for most conveyor and pump cycling — if you're pushing AC-4 reversing or inching duty, it drops to 250 ops/h, so plan your cycle count accordingly.
