The 24 V 50/60 Hz coil pulls in reliably across the full rated voltage range (0.8–1.1 x Us at 50 Hz, 0.85–1.1 at 60 Hz) and holds without chatter down to the dropout threshold. AC-3 duty at 400 V carries 5.5 kW — sized for a standard 7.5 hp motor at that voltage. AC-4 reversing or plugging service is rated 8.5 A at 400 V, so expect some derating if the application cycles hard. Side-by-side mounting is permitted, so multiple units pack tight on the rail without derating the thermal capacity.
The headline AC-1 rating of 10 A at 24 V tells you the resistive switching capacity — heaters, lighting banks, or transformer primaries. AC-4 at 8.5 A is the figure to watch if the contactor sees inching or reversing duty; that's the wear-and-tear number that drives contact life. The mechanical life of 30 million operations is typical for S00 — the electrical life will be lower and depends on the switching category and load current. That's the selectivity data a panel designer needs for the upstream protection scheme. The enclosure is IP20 on the front and at the terminals — suitable for a clean, dry cabinet.

Panel integration
The 45 mm width and 57.5 mm height on a 72 mm depth footprint means it occupies a standard 2.5-module width on the DIN rail. Screw terminals are accessible from the front; the IP20 rating means no finger-safe covers are required inside a locked cabinet. Side-by-side mounting without gaps saves rail space when grouping multiple contactors for a motor control center.
