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.
