This Acti9 iID is a modular and reliable residual current circuit breaker (RCCB). It is a 4P circuit breaker with In rated current of 40A, A-SI type protection class and a 30mA earth leakage sensitivity. This product protects against electrical shock by direct or indirect contact and fire hazards. It performs the function of disconnection of electrical circuits in case of earth fault. Its unique Visitrip indicator reduces intervention time by showing the faulty device with a mechanical indicator on front face. This product also has a VisiSafe window with a green strip on the toggle indicating full opening of the poles allowing downstream maintenance This product is compliant with EN/IEC 61008-1 standard.
