Siemens 3RU2116-1EB0-ZW97 is a SIRIUS thermal overload relay, Size S00, Trip Class 10. Rated insulation voltage is 690 V, with AC-3e rated voltage maximum also at 690 V. Switching current ratings vary by control voltage: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 0.22 A at 125 V. Motor power ratings are 1.5 kW at 400 V, 2.2 kW at 500 V, and 3 kW at 690 V. The -ZW97 suffix indicates a variant with a "for message 'Tripped'" note.
Mounting and Integration
Mounts directly onto a contactor via the contactor mounting fastening method — no DIN rail required. The Size S00 footprint (76 mm height × 45 mm width × 70 mm depth) matches the S00 contactor frame. Mounting position is any orientation, simplifying panel layout. Main circuit connections use screw-type terminals accepting 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded conductors. The auxiliary switch is integrated. Screwdriver spec: Pozidriv PZ 2 tip, shaft diameter 5–6 mm. Temperature compensation is active from -40 to +60 °C, ensuring consistent trip performance across the operating range (-40 to +70 °C). Storage and transport range is -55 to +80 °C.
Compliance and Documentation
Substance prohibitance date is 10/01/2009. MTTF at high demand rate is 2,280 years.
