Rated at 37 kW at 500 V and 18.6 kW at 690 V, this contactor handles typical three-phase induction motors in the 30–40 kW range on a 400 V line. Mechanical life is typical 10,000,000 operations. Side-by-side mounting is allowed.
RoHS compliance is dated 05/01/2012, meaning it meets the EU directive for restriction of hazardous substances.
The AC-4 rating at 55 A is the heavy-duty number for plugging or inching; if your application does frequent reversing, that's the rating to size against, not the AC-3 figure. At 24 V DC the contactor can switch 10 A, but at 220 V DC that drops to 0.3 A — the DC switching capability is limited by arc extinction. If you're switching a DC load above a few amps, verify the voltage against the curve; this is primarily an AC switching device. In a washdown environment, you'd need an enclosure around it.
