This Acti9 REDs is a modular residual current circuit breaker (RCCB) with recloser. It is a 2P circuit breaker with 40A In rated current, 30mA earth leakage sensitivity and A type protection class. This product protects against electrical shock by direct or indirect contact and fire hazards. It disconnects of on-load electric circuits already protected against overloads and short-circuits. It restarts automatically after insulation monitoring of the downstream circuit. It is only used on TT and TN-S earthing grounding systems. The Acti9 RED version is dedicated to residential applications. This product is compliant with EN 60557 standard. The (Im/IΔm) rated breaking and making short circuit capacity is 630A. The (Inc/IΔc) conditional rated short circuit current is 6kA. It has a mechanical endurance going up to 4000 cycles. The Ue operational voltage is 230VAC. The Ui rated insulation voltage is 500VAC. The Uimp rated impulse withstand voltage is 4kV. The frequency is 50Hz. It is DIN rail mountable. The width in 9mm pitches is 6. The product colour is light grey (RAL7035). The dimensions are (W) 54mm x (H) 106mm x (D) 82mm. The weight is 278g. According to IEC 60529 standard, the degree of protection is IP20 and IP40 in enclosure. The operating temperature is from -5°C to 40°C. The storage temperature is from -40°C to 70°C.
