Description: Model: NSX 630N Type: Molded Case Circuit Breaker (MCCB) Poles: 3 (Three-phase protection) Rated Current: 630 A Rated Voltage: 690 V AC Application: The NSX 630N is used to protect electrical circuits from overload, short-circuit, and phase failure. It is commonly used in industrial power distribution, motor protection, and large electrical installations. The breaker is ideal for protecting high-power circuits in commercial and industrial environments. Mounting: Panel mounted or DIN rail mounted Standards Compliance: IEC 60947-2, UL 489, CSA C22.2, CE marking Parameters: Rated Current (In): 630 A Number of Poles: 3 (for three-phase systems) Rated Voltage (Ue): 690 V AC (suitable for industrial power applications) Breaking Capacity (Icu): 50 kA (at 400 V AC) – This means the circuit breaker can safely interrupt fault currents of up to 50,000 A. Tripping Characteristics: Adjustable thermal-magnetic tripping characteristics for overload protection and short-circuit protection. Thermal Protection: Adjusts to prevent damage from prolonged overloads. Magnetic Protection: Provides fast disconnection during short-circuit conditions to protect the system from immediate damage. Rated Frequency: 50/60 Hz Mechanical Durability: 20,000 cycles Electrical Durability: 10,000 cycles Rated Insulation Voltage (Ui): 690 V Rated Impulse Withstand Voltage (Uimp): 8 kV Temperature Range: -5°C to +40°C Auxiliary Contacts: Optional auxiliary contacts (NO or NC) for remote control or signaling functions Connection Type: Screw terminals
