Specifications: Type: Molded Case Circuit Breaker (MCCB) Number of Poles: 3P (3 poles) – Suitable for three-phase systems Current Rating: 250A Rated Voltage: Typically 400V (for three-phase systems) Rated Frequency: 50/60 Hz Tripping Characteristics: Adjustable: The NSX series allows for adjustable thermal and magnetic settings, which helps tailor the protection to the needs of the installation. The 2.2 refers to the adjusted settings available for the breaker’s protection functions. Breaking Capacity: Typically 25 kA at 415V (maximum fault current the breaker can safely interrupt) Protection Features: Thermal Overload Protection: Protects against prolonged overloads by automatically disconnecting the circuit when the current exceeds the set level for a predetermined period. Magnetic Short-Circuit Protection: Instantly trips the breaker when a short circuit occurs, minimizing damage to electrical components and reducing the risk of fire or further faults. Adjustable Settings: The breaker’s settings can be adjusted to match specific circuit requirements, providing better flexibility and optimization for varying loads and conditions. Shunt Trip and Under-Voltage Release Options: Optional accessories for remote tripping and undervoltage protection. Compliance: Complies with international standards such as IEC 60947-2 for low-voltage circuit protection and IEC 60947-4-1 for protection of electrical installations.
