ABB 64528556 high-performance industrial circuit breaker


The ABB 64528556 is a high-performance industrial circuit breaker designed for robust electrical protection in low-voltage power distribution systems. Engineered for reliability in demanding environments, this device provides advanced overcurrent and short-circuit protection, ensuring operational safety and minimizing downtime in industrial, commercial, and infrastructure applications. Its compact design integrates thermal-magnetic tripping technology, enabling precise response to both gradual overloads and sudden fault currents. The circuit breaker is compatible with ABB’s modular distribution systems, supporting flexible installation and scalability in panel boards and switchgear.



Technical Specifications:

  1. Model: 64528556 (Tmax T3N 250A 3P)
  2. Pole Configuration: 3-pole (three-phase + neutral connection capability)
  3. Rated Current (In): 250 A
  4. Rated Ultimate Short-Circuit Breaking Capacity (Icu):
    • At 400 VAC: 50 kA (compliant with IEC 60947-2)
  5. Rated Service Short-Circuit Breaking Capacity (Ics): 100% of Icu (50 kA at 400 VAC)
  6. Thermal-Magnetic Trip Characteristics:
    • Thermal Trip: Adjustable from 0.7–1.0 × In (for overload protection)
    • Magnetic Trip: Fixed at 5–10 × In (for short-circuit protection)
  7. Voltage Rating:
    • Rated Operational Voltage (Ue): 690 VAC (50/60 Hz)
    • Rated Insulation Voltage (Ui): 800 VAC
  8. Mechanical Endurance: 20,000 operating cycles (O-C-O test at rated current)
  9. Electrical Endurance: 10,000 operating cycles at 1.1 × In
  10. Connection Type: Front-terminal screw clamps (compatible with 35–150 mm² conductors)
  11. Protection Features:
    • Thermal Protection: Bimetallic strip delays tripping for transient overloads, preventing nuisance trips.
    • Magnetic Protection: Instantaneous trip for high-fault currents (e.g., phase-to-phase shorts), limiting equipment damage.
    • IP Protection Rating: IP20 (front face), suitable for enclosed panel installations.
  12. Operating Temperature Range: -25°C to +70°C (derating required above 40°C).
  13. Compliance Standards: IEC/EN 60947-2, UL 489, CSA C22.2 No. 5-14.
