Product Description

Product Description

Residual Current Breaker with Over-Current protection (RCBO) is a safety device used in electrical systems that combines the functions of a Residual Current Device (RCD) and a Mini Circuit Breaker (MCB). An RCBO is designed to protect both people and equipment by detecting residual currents (leakage currents) and over-currents (overloads and short circuits). It is commonly used in residential, commercial, and industrial applications to enhance the safety and reliability of electrical installations.
