1. 1. ABB 1SDA073725R1 Air Circuit Breaker
    
    Product Description
    
    Low-voltage air circuit breaker (ACB) for large-capacity low-voltage distribution systems, dedicated to main power inlet protection, heavy-load switching, and fault isolation—critical for heavy industry, large data centers, and super-large commercial complexes to ensure safe and stable power distribution.
    
    Key Specs
    
    Rated Current (In): 1250A (frame size); rated breaking capacity (Icu): 100kA (415V AC, 50Hz).
    
    Voltage Rating: 415V AC (max operating voltage); 250V DC (auxiliary circuit).
    
    Protection Functions: Overcurrent (long-time/short-time/instantaneous, 10-100% In adjustable), earth fault protection (5-5000mA, selective tripping with 0-3s time delay).
    
    Mechanical Life: ≥10,000 operations; electrical life (rated current): ≥2000 operations.
    
    Env: -5°C~+40°C, 5%-95% RH (non-condensing), IP30 (enclosed switchboard installation).
    
    Control & Operation: Manual/electric operating mechanism (remote control via Modbus RTU optional); compatible with ABB Ekip Hi-T3 trip units for intelligent management.
    
    Core Advantages
    
    Ultra-high breaking capacity: 100kA at 415V AC handles severe short-circuit faults in 1250A large-capacity systems (e.g., heavy industrial main power inlet).
    
    Precise protection adjustment: Wide-range overcurrent/earth fault settings adapt to mixed heavy loads (large motors + high-power HVAC + industrial equipment).
    
    Large current carrying: 1250A rated current supports high-power scenarios (e.g., multiple 300kW motors in steel plants).
    
    Advanced intelligence: Ekip Hi-T3 trip unit enables real-time current waveform recording, fault event logging, and remote parameter modification.
    
    Applications
    
    Main incoming circuit protection for heavy industrial plants (e.g., steel mills, shipyards) with 1250A power demand.
    
    Core distribution protection in ultra-large data centers (supporting high-density server clusters + backup UPS systems).
    
    Main switchboard protection for super-large commercial complexes (e.g., integrated resorts, exhibition centers) with multi-heavy-load circuits.
    
    Precautions
    
    Wiring: Main circuit use 240mm² copper cables; torque main terminals to 90-95N·m, auxiliary terminals to 8-10N·m—loose contacts cause overheating.
    
    Protection setting: Set long-time overcurrent to 1250A (full load); adjust short-time delay to 1-3s (avoid false tripping from large motor starting current); set instantaneous current to 18×In for inductive loads.
    
    Installation: Mount vertically in switchboards; reserve 30cm clearance above/below for heat dissipation and manual operation (prevents mechanical jamming).
    
    Maintenance: Test trip function quarterly (manual + electric modes); inspect contact surface annually—replace if wear exceeds 30% of original thickness; clean arc-extinguishing chamber every 1.5 years.
    
    Compatibility: Use only ABB-certified Ekip Hi-T3 trip units and accessories; non-approved parts lead to protection failure or mechanical damage.
