Specifications: Type: Molded Case Circuit Breaker (MCCB) with Residual Current Protection (RCD) Number of Poles: 4P (4 poles) – Suitable for three-phase systems with neutral Current Rating: 400A Rated Voltage: Typically 415V (for three-phase systems) Rated Frequency: 50/60 Hz Tripping Characteristics: Thermal Protection: Disconnects the circuit in the event of overload conditions, preventing overheating and damage to equipment or wiring. Magnetic Protection: Provides instantaneous disconnection during short-circuit conditions, preventing damage from high fault currents. Residual Current Protection (RCD): The breaker provides earth leakage protection, disconnecting the circuit if leakage currents exceed a predetermined threshold, ensuring safety against electric shocks. Breaking Capacity: Typically 50 kA at 415V (maximum fault current the breaker can safely interrupt) Protection Features: Overload Protection: Disconnects the circuit in the event of sustained overload conditions to prevent overheating and damage. Short-Circuit Protection: Provides instantaneous disconnection during short circuits, preventing damage to wiring and connected equipment. Earth Leakage Protection: Disconnects the circuit when earth leakage exceeds a preset threshold, providing protection from electric shock hazards. Manual Reset: The breaker can be manually reset after the fault condition is cleared, allowing the system to return to normal operation. Compliance: Complies with IEC 60947-2 (low-voltage circuit protection) and IEC 61008 (residual current devices), ensuring it meets international safety standards.
