Specifications: Type: Molded Case Circuit Breaker (MCCB) Number of Poles: 3P (3 poles) – Suitable for three-phase systems Current Rating: 1250A Rated Voltage: Typically 415V (for three-phase systems) Rated Frequency: 50/60 Hz Tripping Characteristics: Thermal Protection: Offers overload protection by disconnecting the circuit if the current exceeds the rated value for a prolonged period, thus preventing overheating and damage to the system. Magnetic Protection: Provides instantaneous protection against short circuits by disconnecting the circuit immediately to prevent damage from high fault currents. Adjustable Settings: The breaker offers adjustable settings for both the thermal and magnetic protection, enabling customization based on the system’s specific requirements. Breaking Capacity: 65 kA at 415V (maximum fault current the breaker can safely interrupt) Protection Features: Overload Protection: Disconnects the circuit during sustained overload conditions to prevent overheating and possible damage to the circuit or equipment. Short-Circuit Protection: Instantly disconnects the circuit in the event of a short circuit, preventing excessive damage to the system. Manual Reset: After a trip, the breaker can be manually reset once the fault condition has been resolved, restoring normal operation to the system.
