Its headline rating is 25 A in AC-1 utilisation category at ≤415 V, meaning it is sized for resistive loads — heaters, lighting banks, or transformer primaries — not for motor starting (that would be AC-3 duty). The 400 V coil is standard for 400 VAC three-phase panels. It mounts on a plate or DIN rail, occupies 45 mm width, and carries IP2X finger protection on the enclosure. The non-overlap time of 1.5 ms on both energisation and de-energisation between NC and NO contacts is a safety detail — it guarantees that the NC and NO poles never close simultaneously during switching, which matters for interlocking circuits where overlapping conduction would cause a short.
Fire resistance is certified to 850 °C per IEC 60695-2-1.
Environmental limits
Maximum operating altitude is 3000 m. Mechanical robustness is specified for vibration (1.5 Gn open, 3 Gn closed) and shock (7 Gn open, 10 Gn closed) — enough for most industrial panel environments but not for mobile or high-vibration applications.
