Rated insulation voltage is 690 V, and the relay carries auxiliary contact ratings across common control voltages: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, and 1 A at 400 V. Motor power assignments are 1.5 kW at 400 V, 2.2 kW at 500 V, and 4 kW at 690 V. The relay snaps onto the matching SIRIUS contactor (3RT10 series) without additional hardware, keeping the panel layout compact. Screw-type terminals on the main circuit accept 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²) solid or stranded conductors. Mounts directly onto the matching SIRIUS contactor (3RT10 series) via the contactor mounting fastening method — no DIN rail required, though the contactor itself may be DIN-rail mounted. The relay occupies the same S00 footprint as the contactor, so panel fill factor is unchanged. Mounting position is any orientation. Storage and transport range extends to -55 °C to +80 °C. The auxiliary switch is integrated into the relay body — no separate add-on block needed. The tripped condition is signaled by a mechanical flag and an auxiliary contact changeover, with the Note for message \"Tripped\" indicating the relay's status output. Substance prohibitance date is 10/01/2009. MTTF with high demand rate is 2,280 years. Terminal screws accept Pozidriv PZ 2 tips with a shaft diameter of 5…6 mm. The design of the overload release is thermal (bimetal), with manual or automatic reset options available via the front dial.","metaTitle":"Siemens 3RU2116-1FB0-ZX95 SIRIUS Thermal Overload Relay, CLA","metaDescription":"Siemens 3RU2116-1FB0-ZX95 SIRIUS thermal overload relay, Size S00, CLASS 10 trip class, 690 V rated insulation voltage, contactor mounting.
