Electrical Ratings Parameter Specification Frame Size (Iu) 1400 A Rated Continuous Current (In) 2000 A Rated Operational Voltage (Ue) Up to 690 V AC Rated Insulation Voltage (Ui) 1000 V AC Rated Impulse Withstand Voltage (Uimp) 12 kV Rated Frequency 50/60 Hz 3. Breaking & Withstand Capacity (Note: Values depend on the specific voltage. Below are typical values at 415V AC.) Parameter Specification Ultimate Breaking Capacity (Icu) Typically 150 kA or 200 kA @ 415V AC (Must verify based on specific catalog) Service Breaking Capacity (Ics) Typically 100% of Icu (e.g., 150 kA @ 415V AC) Short-Time Withstand Current (Icw) Typically 85 kA for 1 second @ 415V AC Rated Making Capacity (Icm) Typically 220 kA (peak) @ 415V AC 4. Protection Characteristics (Thermal-Magnetic) Parameter Specification Overload Protection (Ir) Fixed. Typically set at the rated current of 2000A. Thermal element provides inverse-time protection. Short-Circuit Protection (Im) Fixed. Magnetic instantaneous trip. Typical setting is approx. 10 x In (20 kA). Tripping Curve Not adjustable. Standard thermal-magnetic curve. 5. Physical & Mechanical Parameter Specification Dimensions (W x H x D) Approximately ~325mm x ~408mm x ~220mm (for the breaker + chassis). Exact dimensions depend on the specific fixed chassis. Weight Approximately ~30 kg (breaker only). Weight increases with chassis. Connection Type Front connection for both line and load sides. Terminals Suitable for busbar or large cable connections (e.g., dual cables up to 2x400mm² per pole). Operating Positions Connected / Test / Disconnected / Withdrawn (specific to draw-out mechanism). 6.
