Residual current circuit breaker devices provide the function of isolation switching and earth larkage protection of electrical circuits.they open a circuit automatically in the event of an earth fault between phase and earth and /or netural and earth. A wide rang of current ratings and sensitivities are acailable. suitable for domestic. commercial and industrial applications.
It has the following features:
In complicance with IEC/EN61008-1
Bilateral busbar wiring capabilities to adapt to the wider use of premises.
With functions of fault indicator.
