Motor power ratings are 3 kW at 400 V, 4 kW at 500 V, and 5.5 kW at 690 V — match these to your motor nameplate, not the contactor frame. Switching capacity varies by control voltage: 2 A at 24 V and 230 V, 3 A at 120 V, 1 A at 400 V, and 0.3 A at 60 V. The 120 V / 3 A rating is the highest — useful for pilot-duty control circuits in North American panels. Temperature compensation is active from -40 to +60 °C, so the trip curve stays accurate across the operating range without manual derating. MTTF of 2 280 years under high-demand rate reflects the thermal design — no moving parts in the sensing element, just a bimetal strip. Size S00 footprint: 45 mm wide, 76 mm high, 70 mm deep — fits standard 45 mm DIN-rail spacing when mounted on the contactor. Main circuit terminals accept 2 × (0.5 to 1.5 mm²) solid or stranded, or 2 × (0.75 to 2.5 mm²) — screw-type with Pozidriv PZ 2 tip, shaft diameter 5 to 6 mm. Auxiliary switch is integrated into the relay housing — no separate add-on block needed for the trip-indication contact. Mounting position is any orientation, simplifying panel layout in tight enclosures.","metaTitle":"Siemens 3RU2116-1HB0-ZX95 SIRIUS Thermal Overload Relay, Cla","metaDescription":"Siemens 3RU2116-1HB0-ZX95 SIRIUS thermal overload relay, Size S00, Trip Class 10, contactor mounting.
