The relay is rated for main circuit voltages up to 690 V, covering 400 V, 480 V, 500 V, and 690 V line supplies. At 400 V it is rated for 0.75 kW motor load; at 500 V also 0.75 kW; at 690 V it steps to 1.1 kW. These power ratings assume a standard three-phase induction motor — the relay's thermal element is sized to the motor's full-load current, not the kW directly, so the actual setting range on the dial must match the motor nameplate FLA. The auxiliary contacts are rated for switching: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, and 1 A at 400 V — these are the signal contacts that feed the 'tripped' indication back to the PLC or annunciator. The note 'for message Tripped' on the listing confirms the auxiliary switch is integrated and wired for that purpose. Fastening method is contactor mounting — no DIN rail adapter needed if paired with a SIRIUS S00 contactor (e.g., 3RT2 series). Main circuit connections are screw-type terminals accepting 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded wire. The auxiliary switch is integrated, so no separate block is required for the trip signal. Temperature compensation is active from -40 to +60 °C, meaning the trip curve stays accurate across that ambient range — important for outdoor or unheated enclosures.","metaTitle":"Siemens 3RU2116-1BB0-ZX95 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens SIRIUS 3RU2116-1BB0-ZX95 thermal overload relay, size S00, Trip Class 10, for contactor mounting.
