Miniature Circuit Breakers


Installation circuit breakers are automatic switching devices designed to protect electrical installations and equipment from overload and fault currents. They are used for switching, conducting, and disconnecting currents under normal operating conditions as well as in special conditions, such as short circuits.

These breakers provide overcurrent protection (overload and short-circuit) and function as disconnection elements for electric shock protection in industrial, construction, and residential applications.

Protection Types:

  • Overload and short circuit: BKN, BKH, BKP, BF series
  • Ground fault and overcurrent/overvoltage: RKP, RKS series
  • Ground fault only: RKN series
  • Surge protection devices: BKS series

Design & Installation:

  • Available in 1, 2, 3, and 4-pole versions, as well as isolators
  • Mountable on 35 mm DIN rail or as plug-in versions
  • Rated voltage: 230/400 V
  • Tripping characteristics: B, C, D according to IEC 60898 for MCB
  • Optional auxiliary contacts

Certifications: CE, KEMA, SEMKO, CQC/CCC, SABS, SASO, GOST, UL1077, SNI
