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: 320A 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 by detecting sustained overcurrents, preventing damage to electrical wiring and connected equipment. Magnetic Protection: Provides instantaneous disconnection in case of short circuits, preventing catastrophic damage to circuits and equipment. Residual Current Protection (RCD): Detects earth leakage currents and disconnects the circuit if leakage exceeds a predetermined threshold, ensuring safety from electric shock hazards. Breaking Capacity: Typically 50 kA at 415V (maximum fault current the breaker can safely interrupt) Protection Features: Overload Protection: Provides protection against sustained overcurrent conditions that could lead to overheating of equipment and wiring. Short-Circuit Protection: Instantaneous disconnection during short circuits, ensuring the protection of electrical equipment from high fault currents. Earth Leakage Protection: Disconnects the circuit when earth leakage exceeds the preset threshold, protecting personnel from electric shocks. Manual Reset: The breaker can be manually reset once the fault condition has been cleared, restoring normal system operation. Compliance: Complies with IEC 60947-2 (low-voltage circuit protection) and IEC 61008 (residual current devices), meeting international safety standards for electrical protection.
