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: 250A Rated Voltage: Typically 415V (for three-phase systems) Rated Frequency: 50/60 Hz Tripping Characteristics: Thermal Protection: Automatically disconnects the circuit in the event of overload conditions, protecting wiring and equipment from heat damage due to sustained overcurrents. Magnetic Protection: Provides instantaneous disconnection during short-circuit events, protecting the electrical system from damage caused by high fault currents. Adjustable Protection Settings: The thermal and magnetic protection settings are adjustable to meet the specific needs of various applications. Residual Current Protection (RCD): Available in certain configurations, this protection ensures safety from earth leakage currents, preventing electric shocks and reducing fire risks. Breaking Capacity: 50 kA at 415V (maximum fault current the breaker can safely interrupt) Protection Features: Overload Protection: Disconnects the circuit when sustained overload conditions are detected, preventing overheating and damage to electrical components. Short-Circuit Protection: Provides instantaneous disconnection during short-circuit conditions, safeguarding the system from high fault currents. Earth Leakage Protection: Offers residual current protection (RCD) in certain configurations, providing safety against earth leakage currents. Manual Reset: The breaker can be manually reset after a fault has been cleared, allowing for restoration of service.
