The rated insulation voltage is 690 V per IEC 60947-4-1, and 600 V per UL 508 and CSA C22.2 No 14 — so it's at home in North American and European panels alike.
Mounts on a rail or plate — the 57 mm depth, 90 mm width, and 58 mm height mean it fits a standard DIN-rail footprint with room for finger-safe wiring. Screw-clamp terminals accept one or two conductors: solid 1.5–4 mm², flexible without ferrule 0.75–4 mm², or flexible with ferrule 0.34–2.5 mm². Tightening torque is 1.3 N·m with a #2 Philips or 6 mm flat-blade screwdriver. Control voltage limits are 0.8–1.15 Uc for operation and 0.1–0.75 Uc for drop-out at <50 °C — so the 24 V DC coil holds in down to about 19.2 V and drops out reliably below 18 V. Operating time is 30–40 ms for coil energisation and NO closing, and 10 ms for coil de-energisation and NO opening. That's fast enough for most reversing applications but not for high-speed synchronous transfer.
