N7(ID) Residual Current Circuit Breakers

Applications

Residual current circuit breakers provide the function, of isolation. switching and earth leakage
protection of electrical circuits. They open a circuit automatically in the event of an earth fault bet
ween phase and earth and /or natural and earth. A wide range of current ratings and sensitivities
are available. Suitable for domestic, commevical and industrial applications.
