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.","metaTitle":"Siemens 3RU2136-4ED0 SIRIUS thermal overload relay, CLASS 10","metaDescription":"Siemens 3RU2136-4ED0 SIRIUS thermal overload relay, Size S2, CLASS 10 trip, 690 V rated, contactor mounting.
