The relay mounts directly onto a contactor (fastening method: contactor mounting), saving DIN-rail space in a panel. Trip Class 10 is the headline here — it governs the overload curve. For a motor that accelerates in under 10 seconds (most IEC standard motors up to about 15 kW), this relay clears without nuisance tripping. The auxiliary contact ratings are given at multiple control voltages: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V — so the signal circuit can be wired into a 24 VDC PLC input or a 120 VAC control loop without derating surprises. The relay carries ATEX certification (DMT 98 ATEX G 001), which means it is approved for use in potentially explosive gas atmospheres — a requirement for Zone 1 or Zone 2 motor circuits in chemical or oil & gas plants. Dimensions are 45 mm wide, 87 mm high, 78 mm deep — a compact S00 footprint that clips onto a contactor without extra DIN-rail slots. That means it can be packed tight against adjacent devices on the same contactor rail, as long as side breathing space is held. The relay carries ATEX certification (DMT 98 ATEX G 001) for explosive gas atmospheres. It is RoHS-compliant (substance prohibitance date 07/01/2006). Surge voltage resistance rated at 6 kV. Relative humidity tolerance during operation is 100 % — suitable for condensing environments inside a sealed panel. The protection class on the front is IP20, finger-safe.","metaTitle":"Siemens 3RU1116-1CB0-ZW97 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens 3RU1116-1CB0-ZW97 SIRIUS thermal overload relay, size S00, Class 10 trip, 3-pole, screw terminals, ATEX certified, IP20 front, current production.
