The Siemens SIRIUS 3RU2116-0JB0-ZW96 is a thermal overload relay in size S00, designed to protect motor circuits against overload and phase loss.
Rated insulation voltage is 690 V, and the relay handles auxiliary switching at multiple control voltages: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, and 1 A at 400 V. The auxiliary switch is integrated — no add-on needed. Power dissipation per pole is 1.6 W, so panel thermal rise stays manageable in a crowded enclosure.
Mounts directly onto a contactor — fastening method is contactor mounting, not DIN rail. Accepts 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) solid or stranded wire. Overall dimensions: 45 mm wide, 76 mm high, 70 mm deep — fits the S00 footprint common across the SIRIUS family.
