Siemens 3RV6011-1FA15 Motor Protection Circuit Breaker
Product Overview
The Siemens 3RV6011-1FA15 is a compact, thermal-magnetic motor protection circuit breaker (MPCB) from the SIRIUS 3RV6 series, designed for comprehensive protection and control of three-phase induction motors and general electrical loads. It integrates overload, short-circuit, and phase-failure protection in a single device, serving as a reliable switching and protective component for low-voltage industrial power systems. This model is optimized for motors up to 1.5 kW (at 400 V AC) and is widely used in conveyor systems, pumps, fans, compressors, and small industrial machinery.
Main Functions
- Overload Protection
- Equipped with a Class 10 thermal tripping mechanism, it provides precise, time-delayed protection against sustained overcurrents, motor stalling, and excessive starting currents.
- Adjustable overload current setting range: 3.5–5 A, allowing fine-tuning to match specific motor rated currents.
- Phase-failure sensitivity: Detects unbalanced phase currents and trips to prevent single-phasing damage to motor windings.
- Short-Circuit Protection
- Instantaneous magnetic tripping for short-circuit events, with a high breaking capacity of 100 kA at 400 V AC, ensuring rapid fault isolation.
- Current-limiting design minimizes arc energy and downstream equipment stress during short circuits.
- Manual Control & Indication
- Front-mounted rotary operating knob for manual ON/OFF switching and local operation.
- Integrated 1 NO + 1 NC auxiliary contact block for remote status signaling and interlocking with control circuits.
- System Compatibility
- Suitable for use in TN, TT, and IT power systems (with appropriate system considerations for IT networks).
- Complies with IEC 60947-4-1 and VDE 0660 standards for motor control and protection devices.
