This Acti9 iID is a modular and reliable residual current circuit breaker (RCCB). It is a 4P circuit breaker with an in-rated current of 63A, A-type protection class and a 100-mA earth leakage sensitivity. This product protects against electrical shock by indirect contact and fire hazards. It performs the function of disconnecting electrical circuits in the event 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 10 kA. The electrical endurance is up to 15,000 cycles. The mechanical endurance is up to 20,000 cycles. The Ue operational voltage is 380 VAC to 415 VAC. The UI-rated insulation voltage is 500 VAC. The Uimp-rated impulse-withstand voltage is 6 kV. The frequency is 50 Hz or 60 Hz. It is DIN rail-mountable. The width in 9-mm pitches is 8. The product colour is white (RAL9003). The dimensions are (W) 72mm x (H) 91mm x (D) 73.5mm. The weight is 0.37kg. It has an IP20 degree of protection. It becomes IP40 once in a modular enclosure, according to the IEC/EN 60529 standard. The operating temperature is from -25°C to 60°C.
