The AC-3 rated maximum voltage is 690 V, so the relay can be used on 400 V and 690 V line-to-line systems common in European and IEC-sourced panels. The power loss in hot operating state is 4.8 W total, 1.6 W per pole — this matters for enclosure thermal rise calculations when the relay is packed inside a small glanded box. The main circuit terminals accept solid conductors: 2×(0.5…1.5 mm²) and 2×(0.75…2.5 mm²), plus AWG equivalents 2×(20…16) and 2×(18…14) and 2×12. Finely stranded conductors with core-end processing use the same cross-section ranges. That covers standard power wiring for motors up to the relay's rated current range — typically 0.1…0.4 A or similar low-range setting, depending on the specific 3RU1116 variant. The auxiliary contact terminals are rated for 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, and 1 A at 400 V, which is sufficient for signalling back to a PLC input or a contactor coil. Mounting is contactor mounting — the relay clips onto the contactor's body, not onto a DIN rail. The mounting position allows a vertical mounting surface with ±135° rotation and ±45° tilt to front and back. That zero-clearance stacking on four sides means the relay can be packed tight against other SIRIUS S00 components in a motor control centre row, provided the side gap of 6 mm is observed for heat dissipation. ## Physical dimensions and identification Width 45 mm, height 87 mm, depth 78 mm. The Size S00 form factor is the smallest in the SIRIUS relay family, designed for motor ratings up to about 7.5 kW at 400 V AC-3, depending on the specific setting range. The product brand name is SIRIUS, and the product designation is thermal overload relay.","metaTitle":"Siemens 3RU1116-0EB0 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU1116-0EB0 SIRIUS thermal overload relay, Size S00, Trip Class CLASS 10, 3-pole, contactor mounting, IP20 front.
