The relay is rated for main circuit voltages up to 690 V and operates at 50/60 Hz. Temperature compensation is active from -40 to +60 °C, so the trip curve stays accurate across the panel's ambient range. ## Auxiliary contact ratings — what each voltage means for your control circuit The integrated auxiliary switch provides a 'tripped' signal contact. At 60 V it drops to 0.3 A, and at 220 V to 0.11 A. These are the make/break ratings for the signal circuit — match your PLC input or indicator lamp draw to the appropriate voltage row. The contact is mechanically linked to the overload mechanism — when the bimetallic strip deflects past the trip threshold, the auxiliary contact changes state. No separate power supply needed for the trip signal; it's a dry contact rated for the voltages listed. ## Mounting and wiring — fits the SIRIUS contactor frame Fastening method is contactor mounting — the relay snaps directly onto the matching SIRIUS contactor of size S00, sharing the same DIN-rail footprint. The auxiliary circuit uses the same spring-clamp technology. A 3 mm diameter screwdriver shaft is specified for actuating the terminal levers. Dimensions: 87 mm height, 45 mm width, 70 mm depth. The S00 frame keeps the relay compact — it fits alongside the contactor without extending the panel depth beyond the contactor's own envelope. The relay is temperature-compensated across the operating band, so the trip point doesn't drift with panel heat. Lifecycle status is current production. The relay is quoted to order against your BOM quantity — availability and pricing confirmed at RFQ time.","metaTitle":"Siemens 3RU2116-0FC0 SIRIUS Overload Relay, CLASS 10, S00","metaDescription":"Siemens 3RU2116-0FC0 SIRIUS thermal overload relay, CLASS 10 trip, size S00, 690 V rated.
