Maximum mechanical switching frequency under AC-3 duty is 1 000 operations per hour, matching the AC-3e rating. For AC-1 resistive loads the limit is 800 operations per hour, while AC-4 (plugging / inching) drops to 130 operations per hour. The arcing time is specified at 10 to 15 ms. The auxiliary switch is included as standard.
Physical envelope: 120 mm wide, 172 mm tall, 170 mm deep. The contactor mounts via screw fixing, with four 9 mm diameter mounting holes. These clearances must be maintained for proper arc quenching and heat dissipation.
