Siemens Industrial Controls 3RU2116-1GB0 Overload Relay
The Siemens 3RU2116-1GB0 is a high-performance thermal overload relay designed for precise motor protection in industrial and HVACR environments. Engineered for direct mounting onto SIRIUS 3RT2015 through 3RT2018 contactors (Size S00), this unit provides reliable current-dependent protection against excessive temperature rise caused by overloads or phase failures. It features an adjustable setting range of 4.5 to 6.3 Amps, allowing technicians to fine-tune protection based on specific motor nameplate data. With its Class 10 trip characteristic, the relay ensures a rapid response time of 10 seconds or less during overcurrent events, preventing winding damage and extending equipment life.
Built for demanding field conditions, the 3RU2116-1GB0 includes integrated 1NO + 1NC auxiliary contacts for fault signaling and contactor control. Contractors can easily toggle between manual and automatic reset modes using the selector switch, while the built-in STOP and TEST functions allow for routine circuit verification without full disconnection. The screw terminal design ensures secure, vibration-resistant terminations for both main and control circuits. This relay is atmosphere-compensated and supports 690V operating voltages, making it a standard choice for motor starter applications requiring robust phase loss sensitivity and ambient temperature stability.
Key Benefits:- Precise Current Adjustment: Rotary dial supports 4.5-6.3A FLA settings for exact motor matching.
- SIRIUS Modular Compatibility: Optimized for seamless mechanical and electrical connection to S00 frame contactors.
- Phase Failure Sensitivity: Advanced bimetallic detection protects equipment from damage during unbalanced load conditions.
- Dual Reset Modes: Flexibility for local manual intervention or remote automatic system recovery.
- Durable Construction: Rated for ambient temperatures from -40°C to +70°C, suitable for harsh mechanical rooms.
- Does this relay support single-phase applications? Yes, for single-phase AC or DC loads, verify that all three bimetal strips are connected in series to maintain proper tripping characteristics.
- Can it be mounted independently of a contactor? Yes, the 1GB0 can be used for stand-alone installation when paired with the appropriate S00 terminal bracket accessory.
- What is the difference between Class 10 and Class 20? This Class 10 relay is designed for motors with normal starting times, tripping within 10 seconds at 7.2x the set current.
