Parameters 1. General Specifications Parameter Specification Product Series Compact NSX Model SH31404P11A2000 Description 1400A Frame, 2000A Rated Current, 3P, Fixed Thermal-Magnetic Trip, Draw-Out Version Type Molded Case Circuit Breaker (MCCB) Mounting Style Withdrawable / Draw-Out (for fixed-mounted chassis) Number of Poles 3 Poles Trip Unit Type Fixed Thermal-Magnetic (Non-adjustable) Operation Mechanism Manual (stored-energy mechanism) 2. 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 Operating Positions Connected / Test / Disconnected / Withdrawn (specific to draw-out mechanism). 6. Environmental & Standards Parameter Specification Ambient Operating Temperature -25°C to +70°C (with derating above 40°C) Storage Temperature -40°C to +85°C Relative Humidity < 95% (non-condensing) Altitude Up to 2000m without derating. Protection Degree (IP) IP30 (typical for breaker in chassis mounted inside an enclosure) Standards & Certifications IEC 60947-2, GB 14048.2 (CCC), CE, RoHS compliant.
