It's a general-purpose switching device for motor loads up to 11 kW at 690 V or 7.5 kW in AC-2 duty at 400 V, and resistive loads up to 10 A in AC-12 service. The coil pulls in at 0.8 to 1.1 times rated voltage at 50 Hz, so it's tolerant of a sagging line.
Front face is IP20, terminals are IP00 — standard for panel interior where the enclosure provides the outer seal.
Main circuit terminals are screw-type, accepting 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, up to 2x 4 mm² solid max. For stranded wire, the range is 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²), with a single 10 mm² max. AWG equivalents are 2x (16 to 12) solid or 2x (14 to 10) stranded, single 8 AWG. That's enough for the full rated current without pigtailing.
