1. RCD residual current devices provide complete protection for final circuits (against overcurrents and insulation faults):
> protection for users against electric shocks by direct and indirect contacts.
> protection of the installations against fire risks.
2. RCCB residual current circuit breakers provide a protection for users against electric shocks by direct contacts
3. MCB circuit breaker which combine the following functions:
> circuit protection against short-circuit currents,
> circuit protection against overload currents,
> fault tripping indication by red mechanical indicator
> Plug-on system (Fast, easy installation, No connection errors, Safety)
> Positive contact indication
> Operating test button on the front panel
> Fault tripping is indicated by a red mechanical indicator on the front face
> Fast contact closure
> Legacy installations
