The integrated auxiliary switch signals the tripped state directly to the PLC or annunciator. CLASS 10 is the trip class — the relay opens the circuit within 10 seconds under locked-rotor current. That matches most standard 3-phase induction motors; CLASS 20 or 30 would be needed for high-inertia loads like fans or flywheels. At 400 V rated value it is sized for 22 kW, and at 690 V rated value for 45 kW. The auxiliary switch contacts are rated across a range: 2 A at 24 V, 3 A at 120 V, 1 A at 400 V, 0.75 A at 690 V — enough for a PLC input or a contactor coil, but check the load type (resistive vs inductive) for DC circuits. Designed for stand-alone installation — mounts directly to the contactor or on a DIN rail via an adapter. Screw-type terminals on the main circuit accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded wire. The main contact terminals are M6. A Pozidriv PZ 2 screwdriver tip with a 5–6 mm shaft diameter is specified. Mounting position is any. Temperature compensation is active from -40 to +60 °C, meaning the trip curve stays accurate across that span. The substance prohibitance date (RoHS/REACH compliance) is 10/15/2014.","metaTitle":"Siemens 3RU2136-4HB1 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU2136-4HB1 SIRIUS thermal overload relay, CLASS 10 trip, 690 V rated, 22 kW at 400 V.
