Type: Residual Current Circuit Breaker with Overload Protection (RCCB with Overcurrent Protection) Rated Current (In): 20A Poles: 4P (Four-Phase: Three-Phase + Neutral) Voltage Rating: Nominal Voltage: 400V AC (Three-Phase with Neutral) Rated Voltage Range: 380-415V AC Breaking Capacity (Icu): Icu (Ultimate Breaking Capacity): 10 kA Protection Features: Overload Protection: Thermal overload protection to prevent damage caused by excessive current or prolonged overcurrent. Short-circuit Protection: Magnetic short-circuit protection to quickly disconnect the circuit in case of a short-circuit fault. Residual Current Protection: Provides protection against earth leakage currents by detecting and disconnecting the circuit if a leakage current exceeds the threshold (typically 30mA). IΔn (Residual Current Sensitivity): 30mA or 300mA (depending on model variant). Phase Loss Protection: Protects against phase loss or phase imbalance, ensuring that the connected equipment is not exposed to harmful conditions. Manual Reset: Manual reset function after tripping for easy reactivation of the circuit. Certifications: IEC 61008-1 compliant IEC 60947-2 compliant CE Marked for compliance with European safety standards UL certified for global use Mounting: DIN Rail Mounted for easy installation in electrical distribution panels, motor control centers, and protection circuits.
