Residual current circuit breakers (RCCBs)

Residual current circuit breakers (RCCBs) are used to protect humans & installation from insulation faults in residential & commercial applications.

RCCBs for standard applications (class AC)

Technical details

  • Conforms to IEC 61008-1, IS 12640(Part 1):2008/IEC 61008-1:1996
  • Ratings - 25A, 40A, 63A, 100A
  • No. of poles - 2P & 4P
  • Sensitivity - 30mA, 100mA & 300mA
  • Earth fault trip indicator on front face

RCCBs for electrically disturbed networks (Hi type)

Hager Hi RCCBs are designed to provide effective protection in electrically
disturbed networks.They ensure reliable protection to people & installation
in networks having pulsated DC, harmonics & transients currents
(avoids "blinding") while maintaining continuity of supply
(avoids "nuisance tripping").

Technical details

  • Conforms to IEC 61008-1
  • Ratings - 25A, 40A, 63A
  • No. of poles - 2P & 4P
  • Sensitivities - 30mA & 300mA
  • Earth fault trip indicator on front face

Typical applications of RCCBs

Applications of Class AC RCCBs
  • Residential apartments & villas
  • Small offices
  • Shops
Applications of Class Hi RCCBs
  • IT parks,BPOs & call centres
  • Large offices
  • Commercial spaces like malls, multiplexes, recreational places
