These are the AC-3e motor switching ratings — the values that matter for sizing to a specific motor nameplate. Mounts directly to the contactor — no DIN rail required. The S2 size mates with the corresponding SIRIUS contactor frame. Fastening uses M6 screws for the main circuit connections. The auxiliary switch is integrated and uses Pozidriv PZ 2 screwdriver tips with a 5–6 mm shaft diameter. ## Auxiliary contact ratings The integrated auxiliary contact handles 2 A at 24 V, 3 A at 120 V, and 2 A at 230 V AC. For DC switching: 0.3 A at 60 V, 0.22 A at 110 V or 125 V, and 0.11 A at 220 V. These are the contact ratings for the trip-indication circuit — match them to the PLC input or signal lamp load. ## Environmental range and compliance Operates from -40 to +70 °C with temperature compensation active across -40 to +60 °C — the relay adjusts its trip curve to ambient so motor protection stays accurate regardless of panel temperature. The relay carries a substance prohibitance date of October 15, 2014, indicating RoHS compliance per Siemens documentation. Sourced through authorized distribution; quoted to order against the BOM quantity. The 3RU2136-4HD0 carries a note for message \"Tripped\" — this is the auxiliary contact signal that indicates the relay has operated. Useful for wiring a remote trip indication into the control system.","metaTitle":"Siemens 3RU2136-4HD0 SIRIUS Overload Relay, CLASS 10","metaDescription":"Siemens 3RU2136-4HD0 SIRIUS thermal overload relay, CLASS 10 trip, 22 kW at 400 V, 50 A at 480 V.
