An integrated auxiliary switch provides a \"Tripped\" signal, rated for switching at various control voltages: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, and 1 A at 400 V. It is rated for main circuit voltages up to 690 V and can protect motors up to 0.75 kW at 400 V, 1.1 kW at 500 V, and 1.5 kW at 690 V. The relay is temperature-compensated across -40 to +60 °C, ensuring consistent trip performance regardless of ambient conditions in the enclosure. This overload relay is designed for direct contactor mounting — it snaps onto the bottom of a SIRIUS contactor without additional hardware. The mounting position is unrestricted, so it can be installed horizontally, vertically, or flat in the panel. Main circuit connections use screw-type terminals accepting 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) solid or stranded wire. The auxiliary contact is integrated into the relay body, so no separate block is needed for the trip signal. Terminal screws require a Pozidriv PZ2 tip with a 5–6 mm shaft diameter. The relay carries a substance prohibition compliance date of October 1, 2009, indicating it meets RoHS and similar material restrictions. MTTF is listed at 2,280 years under high-demand rate operation, reflecting the reliability expected in continuous-duty industrial applications.","metaTitle":"Siemens 3RU2116-1CB0-ZW97 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens SIRIUS 3RU2116-1CB0-ZW97 thermal overload relay, size S00, Class 10 trip.
