Specifications General Product Type: Molded Case Circuit Breaker (MCCB) Model: NSX100N Configuration: 3P (three-pole) Rated Current (In): 80A Mounting: DIN rail or fixed panel mounting Application: Overload and short-circuit protection for three-phase electrical systems and distribution circuits Electrical Ratings Rated Operational Voltage (Ue): 400V AC (Three-phase) Rated Insulation Voltage (Ui): 690V AC Rated Impulse Withstand Voltage (Uimp): 8kV Short-Circuit Withstand Capacity (Icu): 25kA Rated Frequency: 50/60Hz Overload Protection: Thermal mechanism Short-Circuit Protection: Magnetic mechanism Protection & Trip Characteristics Thermal Overload Protection: The thermal element trips when a sustained overload condition occurs, offering protection against damage due to prolonged overcurrent. Magnetic Short-Circuit Protection: The magnetic trip responds to high, instantaneous short-circuit conditions, preventing significant damage to equipment. Trip Characteristics: Typically features a C-curve, suitable for general-purpose circuits like motors, lighting, and control equipment that may experience moderate inrush currents. Adjustable Settings: The trip unit offers adjustable settings for overload and short-circuit protection, allowing customization based on the application requirements. Mechanical & Environmental Degree of Protection: IP20 (front face) Housing: Compact, modular design for easy integration in distribution boards and panelboards Cable Connections: Screw terminals for secure electrical connections Mechanical Durability: Rated for 10,000 operating cycles Operating Temperature Range: -5°C to +40°C Humidity Range: Suitable for standard indoor environments Pollution Degree: Suitable for industrial environments with typical levels of contamination Accessories & Options Shunt Release: Optional for remote tripping Auxiliary Contacts: Available for remote monitoring and status signaling Undervoltage Release: For additional protection against undervoltage conditions Remote Signaling: Can be equipped with options for remote fault indication and status feedback
