Specifications: Type: Molded Case Circuit Breaker (MCCB) Number of Poles: 3P (3 poles) – Suitable for three-phase systems Current Rating: 400A Frame Size: 400F (indicating the frame size for the 400A version) Rated Voltage: Typically 415V (for three-phase systems) Rated Frequency: 50/60 Hz Tripping Characteristics: Thermal Protection: Provides overload protection, disconnecting the circuit if the current exceeds the rated value for an extended period to prevent overheating and damage to the wiring. Magnetic Protection: Offers instantaneous protection against short circuits by rapidly disconnecting the circuit to prevent damage from high fault currents. Adjustable Settings: The thermal and magnetic settings are adjustable, allowing the user to fine-tune the protection to meet specific application needs. Breaking Capacity: 50 kA at 415V (maximum fault current the breaker can safely interrupt) Protection Features: Overload Protection: Disconnects the circuit when it experiences prolonged overload conditions, protecting electrical components and wiring. Short-Circuit Protection: Provides instantaneous disconnection during short-circuits, ensuring that the system is protected from the damaging effects of high fault currents. Manual Reset: After the breaker trips, it can be manually reset once the fault is cleared.
