At 120 V it's rated 3 A, which covers most North American control transformer circuits without a contact rating derate. Higher-voltage ratings drop off: 1 A at 400 V, 0.75 A at 690 V — fine for signal feedback to a VFD or remote I/O, but not for power switching. ## Environmental range and temperature compensation Temperature compensation is active from -40 to +60 °C, meaning the trip curve stays accurate without manual adjustment across that band — relevant for enclosures near steam lines or chillers. ## Lifecycle and sourcing — active production, quoted to order Substance prohibitance date of 03/01/2017 confirms RoHS/REACH compliance documentation exists — relevant for EU and pharmaceutical validation dossiers.","metaTitle":"Siemens 3RU2146-4JD1 SIRIUS Overload Relay, Class 10, S3","metaDescription":"Siemens 3RU2146-4JD1 SIRIUS thermal overload relay, Class 10 trip, S3 frame, 30 kW at 400 V.
