This Acti9 iID is a modular and reliable residual current circuit breaker (RCCB). It is a 4P circuit breaker with 25A rated current, 30 mA earth leakage sensitivity, and AC type protection class. This product protects against electrical shock from direct or indirect contact and fire hazards. It performs the function of disconnecting electrical circuits in the event of an earth fault. Its unique Visitrip indicator reduces intervention time by showing the faulty device with a mechanical indicator on the 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 the 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. It has an electrical endurance of up to 15000 cycles and a mechanical endurance of up to 20000 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. According to the IEC 60529 standard, the degree of protection is IP20 and IP40 in the enclosure.
