The 3RU2136-4ED1 carries a 15 kW rating at 400 V, and also 18.5 kW at 500 V and 30 kW at 690 V — so it covers 400 V and 690 V motor circuits without needing a different frame. The auxiliary contact ratings are given for multiple voltages: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V — these are the contacts that signal the trip condition back to the PLC or annunciator. The relay dissipates 4.6 W per pole, which matters for enclosure heat rise if you're packing several in a small panel. This relay is designed for stand-alone installation — it mounts directly to the mounting plate or DIN rail, not piggybacked on a contactor. The main circuit terminals are screw-type, accepting 2x (0.5 to 2.5 mm²) solid or stranded wire, with a Pozidriv PZ 2 screwdriver tip. Temperature compensation is active from -40 to +60 °C, so the trip curve stays accurate across the working range.","metaTitle":"Siemens 3RU2136-4ED1 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU2136-4ED1 SIRIUS thermal overload relay, Class 10, 15 kW at 400 V, 690 V rated insulation.
