The contactor frame is 70 mm wide, 140 mm tall, and 152 mm deep, so it occupies a standard S3 footprint in the enclosure. The coil termination uses screw-type terminals; main power wiring accepts solid conductors from 2.5 to 16 mm² or stranded from 6 to 70 mm².
The AC-3 switching frequency is rated at 1 000 operations per hour — that's about one cycle every 3.6 seconds, which covers most conveyor and pump duty cycles without derating. The AC-4 maximum is 300 operations per hour, reflecting the heavier electrical wear of plugging or inching loads. The auxiliary switch is built in, with contact ratings from 10 A at 24 V down to 0.3 A at 220 V — enough for PLC inputs or relay coils in the same panel.
