It carries two normally-open instantaneous contacts rated for switching at various control voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. That covers the common control-circuit voltages you'll find across European and North American panels — 24 VDC, 230 VAC, 400 VAC line-to-line, and 690 VAC for heavy industrial.
The shock resistance of 10g for 5 ms and 5g for 10 ms is enough for mounting on vibrating machinery — think compressors or punch presses. The solid wire range of 2x (0.25 to 2.5 mm²) matches standard control wiring — no need for special ferrules or oversized terminals.
