Technical Specifications
  • Frame: SF (Spectra F-frame)
  • Poles: 3
  • Rated Current: 250 A (field-changeable via front rating plug)
  • Voltage: 600 V AC max (UL); 220–690 V AC (IEC)
  • Interrupting Capacity: 200 kA @ 240 V, 100 kA @ 480 V, 25 kA @ 600 V (UL); 18 kA @ 690 V IEC
  • Trip System: Digital solid-state RMS sensing (true-RMS, handles non-sinusoidal/harmonic currents)
  • Adjustments: Long-time delay (fixed by rating plug), short-time, instantaneous (adjustable)
  • Dimensions: 10.12 × 4.12 × 3.81 in (H×W×D)
  • Enclosure: Thermoset polyester + metal frame, NEMA 1/3R/4/12 compatible
  • Certifications: UL 489, CE
    Functional Features: Current-limiting design, front-mounted interchangeable rating plug, accessory ready (aux contact, shunt trip, alarm).
    Working Principle: Continuously samples phase currents, computes RMS value digitally, compares against time-current curve; trips solid-state actuator on overload/short-circuit.
    Application: Main incoming breaker for MCC, generator paralleling switchgear, 250 A feeder protection in plants.
    Installation & Notes: Bolt-on or lug termination; torque to GE spec; obsolete—verify retrofit kit (ABB Tmax XT) before replacement order.
