Residual Current Circuit Breakers


Residual Current Circuit Breakers are placed directly upstream of the loads and are designed for protection against ground fault.

Residual Current Circuit Breakers with Over-current function (RCBO) are designed for protection against ground fault as well as over-current.
They are ideal for the protection of circuits in industrial, commercial, and residential sectors, and ensures the following functions: isolation and protection of people against direct contact.
