RCBO Protection

Combined residual current and overcurrent protection for individual electrical circuits.

RCBO Protection

Technical description

RCBO devices combine the functions of an MCB and an RCD in one modular device.

They are useful when individual circuit protection and residual current protection are required without grouping multiple circuits under one RCD.

Typical use cases

  • Individual circuit residual current protection
  • Residential distribution boards
  • Critical circuit separation
  • Renovation boards with limited space
  • Technical circuits requiring dedicated protection
