Abstract: This study is focused on a residual-current circuit breaker (RCCB) and its eventual operation malfunction due to direct current components. This problem is associated with magnetic phenomena inside its transformer core. These phenomena are described in detail in the magnetic equations used in a mathematical model created in Simulink. The model incorporates the comparison of individual transformer B/H loop and verifies its reaction to the various residual currents and the correct operation of residual current circuit breaker to achieve results.
