What the 24-32 A rating means for motor control
The 3RA9012-5AG07: This is a GM-SET contactor assembly rated 24-32 A — the range covers standard IEC motor sizes up to about 15 kW at 400 V AC-3 duty, depending on the exact motor full-load current. The 3-pole non-reversing configuration with 1NO-1NC auxiliary contacts handles basic start/stop control; the integral surge suppression protects the coil from voltage spikes during switching.
The 1NO-1NC aux contacts are wired for feedback to the PLC or for a holding circuit; the surge suppressor is pre-wired internally, so no external MOV or RC snubber is needed at the coil terminals.
