Rated operational voltage is 690 V. The relay mounts in any position (stand-alone installation) and connects via spring-loaded terminals accepting 2× (0.5...2.5 mm²) solid or stranded wire. Temperature compensation is active from -40 to +60 °C, keeping the trip curve stable across the panel ambient range. ## Motor power ratings by voltage The 3RU2116-0EC1 carries motor power ratings at several common line voltages: 0.09 kW at 400 V, 0.12 kW at 500 V, and 0.18 kW at 690 V. At 480 V and 600 V the rated current is 0.4 A. These figures define the maximum continuous motor load the relay can protect at each voltage—oversizing the relay beyond these values would delay tripping and risk winding damage. ## Auxiliary contact ratings across voltages The integrated auxiliary switch is rated for the following currents at the stated voltages: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 0.75 A at 690 V. Lower-voltage ratings (60 V: 0.3 A; 110 V: 0.22 A; 125 V: 0.22 A; 220 V: 0.11 A) also apply. These are the maximum switching currents the auxiliary contacts can handle—use them for PLC inputs or contactor coils, not for motor loads. Stand-alone installation means no separate base adapter is required—mount directly and wire through the spring-loaded terminals. The screwdriver shaft diameter is 3 mm with a 3.0 × 0.5 mm tip for terminal actuation. Dimensions: 102 mm height, 45 mm width, 79 mm depth.","metaTitle":"Siemens 3RU2116-0EC1 SIRIUS Thermal Overload Relay, S00, Cla","metaDescription":"Siemens 3RU2116-0EC1 SIRIUS thermal overload relay, size S00, Trip Class 10.

The 3RU2116-0EC1 uses spring-loaded terminals; the 3RU2116-1FC1 may use screw terminals. If the panel was wired for screw terminals, the spring-loaded version will fit mechanically but the wiring method differs — no rewiring of the panel layout is needed, but the terminal interface changes."},{"question":"What compliance documentation does Siemens provide for 3RU2116-0EC1?","answer":"The relay carries a substance prohibitance date of 10/01/2009, indicating RoHS compliance from that date.
