It is a size S00 device designed for stand-alone installation. The trip class is CLASS 10. The relay uses a thermal bimetallic release and is rated for 690 V operating voltage at 50/60 Hz. The insulation voltage at pollution degree 3 is also 690 V. Surge voltage withstand is 6 kV. RoHS compliance is indicated by a substance prohibitance date of 05/01/2012. The relay carries Siemens SIRIUS branding. ## Physical integration and wiring Dimensions are 89 mm high, 45 mm wide, and 80 mm deep. Required spacing to grounded parts at the side is 6 mm. Mounting position is any. Main circuit and auxiliary/control circuit both use screw-type terminals. Main contacts accept 2x (0.5–1.5 mm²) solid/stranded or 2x (0.75–2.5 mm²), with AWG equivalents 2x (20–16) and 2x (20–18) plus 2x 12. Auxiliary contacts accept 2x (20–16) and 2x (18–14) AWG. Tightening torque for main contacts is 0.8–1.2 N·m. Finely stranded with core end processing is also supported: 2x (0.5–1.5 mm²) and 2x (0.75–2.5 mm²). ## Environmental and mechanical withstand Relative humidity during operation is 0–90 %. Shock resistance per IEC 60068-2-27 is 8g / 11 ms. Installation altitude maximum is 2 000 m above sea level.","metaTitle":"Siemens 3RU6116-0CB1 SIRIUS Thermal Overload Relay, 0.18–0.2","metaDescription":"Siemens SIRIUS 3RU6116-0CB1 thermal overload relay, 0.18–0.25 A adjustable, Class 10, size S00, 690 V, 50/60 Hz.

The 3RU6116-0CB1 is a stand-alone installation variant — it does not snap onto a contactor. They are not drop-in interchangeable without rewiring the mounting and wiring scheme."},{"question":"What is the depth of 3RU6116-0CB1?","answer":"The depth is 80 mm.
