Match the control voltage to these limits — the switch is rated for the full 690 V main circuit, but the auxiliary contacts are the bottleneck on higher-voltage control schemes. Fastens directly onto the contactor via the integrated mounting mechanism — no separate base or adapter bracket needed. The screwdriver spec is Pozidriv PZ2 with a 5–6 mm shaft diameter — no special tooling required. Dimensions are 90 mm high, 55 mm wide, 105 mm deep — the S2 footprint fits standard Siemens SIRIUS contactor assemblies without encroaching on adjacent wiring ducts. ## Lifecycle and compliance documentation The substance prohibitance date is October 15, 2014, confirming RoHS compliance for the current manufacturing batch. Temperature compensation is active from -40 to +60 °C, so the trip curve stays accurate across the panel ambient range.","metaTitle":"Siemens 3RU2136-4JD0 SIRIUS Overload Relay, CLASS 10, S2","metaDescription":"Siemens 3RU2136-4JD0 SIRIUS thermal overload relay, CLASS 10 trip, S2 size, 690 V rated, screw terminals.
