Siemens Industrial Controls 3RU2126-1FB0 Relay
The Siemens 3RU2126-1FB0 is a high-performance thermal overload relay designed for precise motor protection in demanding industrial environments. Engineered for direct mounting onto SIRIUS 3RT2 size S0 contactors, this unit provides critical current-dependent protection against overloads and phase failures. With an adjustable setting range of 3.5 to 5.0 Amps, it ensures optimal equipment safety by monitoring the temperature-sensitive bimetal strips within the assembly. This Class 10 tripping relay is built to disconnect the load in 10 seconds or less during an overcurrent event, effectively preventing motor burnout and costly downtime. Unlike light-duty alternatives, the 3RU2126-1FB0 features screw terminals for secure electrical connections and includes 1 NO + 1 NC auxiliary contacts for seamless integration into control circuits. Professionals prefer this Sirius industrial control component for its reliability in both AC and DC applications up to 690V, offering a robust solution for contractors focused on long-term system stability and motor protection.
Key Benefits- Versatile Reset Modes: Features a selectable switch for manual or automatic reset, allowing for flexible troubleshooting and system recovery.
- Phase Failure Sensitivity: Detects imbalances and phase loss early to protect three-phase motors from catastrophic failure.
- Compact S0 Frame: Optimized for the Siemens SIRIUS modular system, saving significant cabinet space through direct contactor integration.
- Environmental Resilience: Rated for operation in temperatures ranging from -40 to +70 °C, suitable for extreme HVACR and industrial conditions.
Can this relay be used with Size S00 contactors?
No, the 3RU2126-1FB0 is specifically designed for Size S0 contactors. For S00 frames, you must select a 3RU2116 series relay to ensure proper mechanical and electrical fit.
Does this unit support single-phase motor protection?
Yes, though primarily used for three-phase systems, it can protect single-phase loads by wiring the poles in series to ensure all bimetal strips are heated uniformly.
What is the difference between Class 10 and Class 20 tripping?
This is a Class 10 relay, meaning it trips within 10 seconds at 600% of the set current. This is standard for most industrial motors; Class 20 is reserved for high-inertia loads with longer start-up times.
