Rated operational current is 4 A at 690 V, 50/60 Hz, with a surge voltage withstand of 6 kV — the insulation coordination covers 400/480 V panels with headroom for transient events on the line side. ## Panel fit and wiring — size S00, stand-alone, any orientation Mounting position is unrestricted, so it fits in vertical or horizontal panel layouts; side spacing to grounded parts needs 6 mm minimum to maintain creepage distances at 690 V. ## Environmental tolerance and compliance Operating ambient spans -40 to +70 °C, with storage/transport down to -55 °C and up to +80 °C — enough for unheated warehouses or outdoor cabinets in temperate climates. Relative humidity 0–90 % non-condensing. Shock rated 8g / 11 ms per IEC 60068-2-27, so it holds calibration under vibration from contactors and motor starters in the same enclosure. RoHS and REACH compliance declared with substance prohibitance date 05/01/2012 — the relay is free of the restricted substances listed in those directives.","metaTitle":"Siemens 3RU6116-1EB1 SIRIUS Overload Relay, 2.8-4 A","metaDescription":"Siemens 3RU6116-1EB1 SIRIUS thermal overload relay, adjustable 2.8-4 A, Class 10, 690 V, screw terminals.
