Rated voltage is 690 V, covering 400 V and 480 V motor circuits common in European and North American panels.
Mounts directly onto the contactor via the fastening method listed as contactor mounting — no separate DIN-rail bracket needed, which saves panel space. The Size S2 form factor (90 mm height, 55 mm width, 105 mm depth) pairs with Siemens S2 contactors like the 3RT1034 series. Screw-type terminals on the main current circuit accept 2× (0.5 to 2.5 mm²) solid or stranded wire; use a Pozidriv PZ 2 screwdriver tip with a 5 to 6 mm shaft diameter.
Auxiliary contact ratings and thermal limits
The integrated auxiliary switch provides signal feedback — the Note for message Tripped indicates this relay has a built-in trip-indicator contact. Its switching capacity varies by voltage: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 0.3 A at 60 V. These are the ratings for the auxiliary contact circuit, not the main power path. Temperature compensation is active from -40 to +60 °C, meaning the trip curve stays accurate across that span without manual adjustment.
