The relay is rated for main circuit voltages up to 690 V and carries a \"Tripped\" message contact (the Note field on this variant signals that auxiliary contact state). The S00 frame size keeps the footprint tight: 45 mm wide, 76 mm tall, 70 mm deep, which fits neatly into a motor control center bucket or small panel enclosure. ## Switching capacity and auxiliary contact ratings The integrated auxiliary switch handles a range of control voltages: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 0.75 A at 690 V. That covers most PLC output cards and control transformer secondaries you'll find in a 24 VDC or 120 VAC panel. For lower-voltage DC circuits, it also switches 0.3 A at 60 V and 0.22 A at 110/125 V. ## Installation and wiring notes The main circuit terminals are screw-type, accepting 2× (0.5…1.5 mm²) or 2× (0.75…2.5 mm²) solid or stranded copper. Use a Pozidriv PZ 2 tip with a 5–6 mm diameter shaft. Temperature compensation is active from -40 °C to +60 °C, so the trip curve stays accurate across most industrial ambient conditions. MTTF with high demand rate is 2,280 years — a reliability figure that supports continuous-duty applications.","metaTitle":"Siemens 3RU2116-1EB0-ZX95 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens SIRIUS 3RU2116-1EB0-ZX95 thermal overload relay, Size S00, CLASS 10 trip, 690 V rated, contactor mounting.
