It carries four normally-open instantaneous contacts, meaning they switch without delay when the coil picks up, and they handle the full rated current curve from 10 A at 24 V down to 0.27 A at 220 V and 1 A at 690 V. The S00 frame size keeps it compact at 45 mm wide and 73 mm deep, sized to snap onto a DIN rail or screw directly into a panel.
That matters when you're feeding a PLC input or a safety relay that sees milliamps; a standard power contactor might oxidise its contacts and miss the signal.
Wiring and integration
Terminals accept solid conductors from 0.25 to 2.5 mm², which covers standard control wiring from 24 AWG to 14 AWG. The screw and snap-on mounting lets you either clip it onto the rail or bolt it directly to a backplate — handy when the rail is full or you're building a sub-panel. The shock resistance of 10g for 5 ms and 5g for 10 ms is enough for most industrial panels but not for direct mounting on a vibrating machine base.
