Design features

Molded Case Circuit Breaker

  • Complies with major international standards and certifications.(IEC,JIS,CE,TÜV,CCC)
  • High performance and compact design breaker by FUJI's ingenious ablation breaking technology.
  • Providing better user friendliness by the standardization of internal accessory parts.(32/50/63/100AF, 125/250AF,400/630/800AF)
  • Material description of major components, compliance with RoHS Directive, and lower environmental impact by Cadmium-free contact. (subject to some exceptions.)

Earth Leakage Circuit Breaker

  • Complies with the major international standards and certifications.(IEC,JIS,CE,TÜV,CCC)
  • High performance and compact design breaker by FUJI's ingenious ablation breaking technology.
  • Pursuit of user friendliness by standardization of internal accessory parts. (32/50/63/100AF, 125/250AF,400/630/800AF)
  • High workability can be obtained since the removal of ELCB wiring is not required at dielectric test during inspection.
  • Contributes to safety and compactness by furnishing new three-phase power supply circuit acts in the event of ground fault even when the loss of one phase occurs in a three-phase system (Required in the revised IEC60947-2).
  • Equipped with the newly developed leakage detection circuit, noise surge performance improves even better.
  • Material description of major components, compliance with RoHS Directive, and lower environmental impact by Cadmium-free contact. (be subject to some exceptions.)
