The auxiliary switch is integrated (no separate block needed) and carries the following contact ratings: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 0.22 A at 125 V / 110 V / 220 V. These are the contacts that signal the \"Tripped\" message back to the PLC or annunciator. Mounts in any position directly onto the contactor — no DIN rail required for the relay itself, though the contactor typically clips onto a DIN rail. The main current circuit uses spring-loaded terminals (cage clamp) accepting 2× (0.5 to 2.5 mm²) solid or stranded wire. Screwdriver shaft diameter 3 mm, tip 3.0 × 0.5 mm for the auxiliary terminals. Dimensions: 70 mm deep, 45 mm wide, 87 mm high. This is the S00 form factor — the smallest SIRIUS overload relay size, fitting contactors in the S00 frame class. ## Motor Power and Current Ratings Motor power ratings at 50/60 Hz: 0.12 kW at 400 V, 0.18 kW at 500 V, 0.25 kW at 690 V. Current ratings at 480 V and 600 V are both 0.5 A. These are the motor-protection settings the relay is designed to match. Substance prohibitance date is 10/01/2009, indicating RoHS compliance (EU RoHS, likely with exemptions as applicable). MTTF with high demand rate is 2,280 years — a reliability figure used for safety-instrumented-system calculations.","metaTitle":"Siemens 3RU2116-0FC0-ZX95 SIRIUS Thermal Overload Relay, Cla","metaDescription":"Siemens 3RU2116-0FC0-ZX95 SIRIUS thermal overload relay, size S00, Trip Class 10, 690 V rated insulation voltage, contactor mounting.
