Specifications: Type: Molded Case Circuit Breaker (MCCB) Number of Poles: 3P (3 poles) – Suitable for three-phase systems Current Rating: 250A Frame Size: NSX250F (denotes the frame size and current rating of the breaker) Rated Voltage: Typically 415V (for three-phase systems) Rated Frequency: 50/60 Hz Tripping Characteristics: Thermal-Magnetic Protection: The breaker provides thermal protection against overloads and magnetic protection for short circuits. Magnetic Trip: Instantly disconnects the circuit when a short circuit occurs, minimizing the risk of damage to electrical components. Fixed Thermal Trip Settings: The thermal protection setting is pre-configured, making it ideal for applications where no adjustments are necessary. Breaking Capacity: Typically 25 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 overheating and equipment damage. Short-Circuit Protection: The breaker trips instantly when a short circuit is detected, protecting the circuit and connected devices. Manual Reset: After tripping, the breaker can be manually reset once the fault condition is cleared.
