This is a Multi GFP residual current circuit breaker (RCCB). It is a 2P circuit breaker with In rated current of 40A, A-SI type protection class and a 26mA earth leakage sensitivity. It protects persons against electric shock by direct contact. It also protects installations against fire risks. The tripping upon fault is indicated by a red mechanical status indicator on the front panel. The A-SI type offers enhanced immunity to electrical disturbances. This product is dedicated to original equipment manufacturers (OEM) and control panel builders in indisutrial and tertiary buildings. It is compliant with IEC/EN 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 a mechanical endurance going up to 20000 cycles. The Ue operational voltage is 240VAC. The Ui rated insulation voltage is 440VAC. The Uimp rated impulse withstand voltage is 6kV. The frequency is 50Hz or 60Hz. It is DIN rail mountable.
