Front-side protection class is IP20, so it's suited for dry indoor cabinets where accidental finger contact is the main concern. The contactor is rated for switching at multiple voltage levels: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V, covering typical control voltages from 24 VDC up to 690 VAC. Contact reliability is specified at one incorrect switching operation per 100 million cycles at 17 V, 1 mA — a solid margin for dry-circuit signal switching. A built-in full-wave rectifier surge suppressor handles coil suppression, so you don't need to add an external flyback diode or RC snubber for standard AC coils.
The screw and snap-on mounting method lets you clip it onto a DIN rail without tools or screw it directly to a backplate. Shock resistance is 10g / 5 ms and 5g / 10 ms, suitable for panels on vibrating machinery or near conveyors.
RoHS compliance is indicated by a substance prohibition date of July 1, 2006, covering the EU RoHS directive. No UL, CSA, or CE listing appears in the evidence, but the SIRIUS series typically carries these for the European and North American markets — verify with the order desk if your project requires specific agency marks.
