Specifications: Type: Molded Case Circuit Breaker (MCCB) Number of Poles: 4P (4 poles) – Suitable for four-wire, three-phase systems (including neutral) Current Rating: 400A Frame Size: 400H (indicating the high-capacity frame suitable for high current applications) Rated Voltage: Typically 415V (for three-phase systems with neutral) Rated Frequency: 50/60 Hz Tripping Characteristics: Thermal Protection: Provides overload protection by disconnecting the circuit when the current exceeds the rated value for an extended period. Magnetic Protection: Provides instantaneous disconnection in the event of a short circuit, ensuring the protection of the circuit and preventing damage to equipment. Adjustable Thermal Settings: The thermal settings can be adjusted to suit various applications and load requirements, allowing for flexible protection. Breaking Capacity: Typically 50 kA at 415V (maximum fault current the breaker can safely interrupt) Protection Features: Overload Protection: Disconnects the circuit when the current exceeds the rated value for a prolonged period, preventing damage to wiring and connected devices. Short-Circuit Protection: Provides instantaneous protection when a short-circuit occurs, ensuring that damage to the system is minimized. Manual Reset: After tripping, the breaker can be manually reset once the fault condition has been cleared.
