Rcbos are a combination of an rccb and a miniature circuit breaker in a compact design for personnel, fire and line protection. For personnel protection and fire protection, the residual current part of the type ac trips in the event of sinusoidal ac residual currents, type a also trips in the event of pulsating DC residual currents. In addition, rcbos type f also detect residual currents with mixed frequencies up to 1 khz. Rcbos with a rated residual current of maximum 30 ma are used for personnel, material and fire protection, as well as for protection against direct contact.
