Specifications: Type: Molded Case Circuit Breaker (MCCB) Number of Poles: 3P (3 poles) – Suitable for three-phase systems Current Rating: 200A Frame Size: 250H (indicating the high capacity frame for large current protection) Rated Voltage: Typically 415V (for three-phase systems) Rated Frequency: 50/60 Hz Tripping Characteristics: Thermal Protection: The thermal protection ensures that the breaker trips if the current exceeds the rated value for a prolonged period, protecting the circuit from overheating. The thermal settings are adjustable, providing flexibility for different load conditions. Magnetic Protection: The magnetic protection provides instantaneous disconnection in the event of a short circuit, preventing severe damage to the circuit. Adjustable Thermal Settings: The thermal trip settings can be adjusted to accommodate different system requirements, making it versatile for a wide range of applications. Breaking Capacity: Typically 36 kA at 415V (maximum fault current the breaker can safely interrupt) Protection Features: Overload Protection: The breaker disconnects the circuit when sustained overload conditions are detected, preventing overheating of cables and equipment. Short-Circuit Protection: Provides instantaneous protection in the event of a short-circuit, ensuring rapid disconnection of the faulted circuit. Manual Reset: After tripping, the breaker can be manually reset once the fault has been cleared.
