That is the standard for standard-start induction motors — pumps, fans, compressors — where the starting transient is brief. For heavy starts (high-inertia loads like centrifuges or crushers) you would step up to Class 20 or 30; for servo or spindle drives you might go Class 5. For a general 400 V motor at 0.55 kW (the rated power at 400 V), this relay matches the thermal curve correctly. Mounts in any position. The main circuit terminals accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded wire with screw-type terminals (M3 screw, Pozidriv PZ 2 tip, 5–6 mm shaft diameter). Temperature compensation is active from -40 to +60 °C, so the trip curve stays accurate across the panel ambient range. The integrated auxiliary switch carries the following ratings: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, 0.75 A at 690 V. At 60 V it is rated 0.3 A; at 110 V and 125 V it is 0.22 A; at 220 V it is 0.11 A. These are the contact ratings for the tripped-signal circuit — use them to size the PLC input or indicator load.","metaTitle":"Siemens 3RU2116-1AB1 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU2116-1AB1 SIRIUS thermal overload relay, Trip Class 10, size S00, 690 V rated, 45 mm wide.
