Specifications: Type: Molded Case Circuit Breaker (MCCB) Number of Poles: 4P (4 poles) – Suitable for three-phase systems with neutral (4-wire systems) Current Rating: 320A Rated Voltage: Typically 415V (for three-phase systems) Rated Frequency: 50/60 Hz Tripping Characteristics: Thermal Protection: Disconnects the circuit when overload conditions are detected, preventing overheating and damage to equipment and wiring. Magnetic Protection: Provides instantaneous disconnection during short-circuit conditions, protecting the system and connected equipment from high fault currents. Adjustable Protection Settings: Both thermal and magnetic protection settings are adjustable, allowing for fine-tuning based on the system's requirements. Residual Current Protection (RCD): Available in certain configurations for earth leakage protection, ensuring personnel safety by disconnecting the circuit when leakage currents exceed a certain threshold. Breaking Capacity: 50 kA at 415V (maximum fault current the breaker can safely interrupt) Protection Features: Overload Protection: Disconnects the circuit when overload conditions persist, preventing damage to electrical components. Short-Circuit Protection: Provides instantaneous protection during short circuits, preventing damage to wiring and connected equipment. Earth Leakage Protection: Provides protection against earth leakage currents, ensuring safety from electric shock and minimizing the risk of electrical fires. Manual Reset: After a fault is cleared, the breaker can be manually reset, restoring normal operation.
