At 110 V and 125 V the rating drops to 0.22 A, and at 220 V to 0.11 A — if your control circuit runs at one of these voltages, verify the auxiliary contact can handle the connected load without derating. The note \"for message 'Tripped'\" on the spec line indicates this variant includes a remote trip-indication contact — it signals the PLC or HMI that the relay has operated, not just the local flag. ## Panel fit, wiring, and environmental limits Fastening method is contactor mounting — it clips directly onto the matching SIRIUS contactor (S00 frame), no DIN rail bracket needed, saving panel width. Mounting position is any orientation, so it fits in tight enclosures without derating for sideways or inverted installation. Dimensions are 45 mm wide, 87 mm high, 70 mm deep — the width matches the S00 contactor footprint, keeping the motor starter assembly compact. Power dissipation per pole is 2.7 W at rated current — three poles dissipate about 8.1 W total, which must be considered in the enclosure thermal budget. MTTF with high demand rate is 2,280 years — a reliability figure that supports use in safety-related applications where the relay is exercised frequently. Substance prohibitance date is 10/01/2009, indicating RoHS compliance per the EU directive effective from that date.","metaTitle":"Siemens 3RU2116-4AC0-ZX95 SIRIUS thermal overload relay","metaDescription":"Siemens 3RU2116-4AC0-ZX95 SIRIUS thermal overload relay, CLASS 10 trip, size S00, 690 V rated, 7.5 kW at 400 V.
