This Acti9 iID is a modular and reliable residual current circuit breaker (RCCB). It is a 4P circuit breaker with 40A In rated current, 100mA earth leakage sensitivity and AC type protection class. This product protects against electrical shock by 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. The (Im/IΔm) rated breaking and making short circuit capacity is 1500A. The (Inc/IΔc) conditional rated short circuit current is 10kA. It has an electrical endurance going up to 15000 cycles and a mechanical endurance going up to 20000 cycles. The Ue operational voltage is 380VAC to 415VAC. The Ui rated insulation voltage is 500VAC.
