The AC-4 rating (same 16 A frame) supports inching and plugging, where the contactor interrupts the motor at full load repeatedly. The coil is 48 V AC, so verify your control transformer taps before wiring — a 24 V DC coil variant exists in the same frame but this order code is fixed at 48 V AC.
Integration notes
Rated operational voltage on the power circuit is 690 V AC 50/60 Hz, so it can be used on 400 V or 480 V line-to-line systems without derating. Mechanical robustness is specified to 10 Gn shocks on Y and Z axes (contactor closed) and 4 Gn vibration at 5-300 Hz — sufficient for machine-mounted applications on conveyors or pumps, but verify against your specific machine vibration profile if mounted directly on a high-impact press or crusher.
Flame retardance meets UL 94 V1 and NF F 16-101/102 (railway fire-smoke-toxicity standards), so the part carries rail-vehicle compliance. Protective treatment conforms to IEC 60068 and DIN 50016 for corrosion resistance. Operating altitude is 2000 m without derating.
