This Resi9 product is an arc fault detection RCBO. It is a 1P+N circuit breaker with 1 protected pole, 6-25A rated current (In) at 30°C and C tripping curve. The operating frequency is 50Hz. The earth leakage protection class is type A with a sensitivity of 30mA. The earth-leakage protection time delay is instantaneous. The breaking capacity (Icn) is up to 6000A at 230VAC with operating frequency of 50Hz, conforming to AS/NZS 61009.1 standard. This Resi9 circuit breaker is compatible with TN-S, TT and IT earthing system. It has a position contact indication suitable for industrial isolation. The electrical endurance goes up to 10000 cycles with operating frequency of 50Hz, conforming to IEC 61009 standard. The mechanical endurance goes up to 20000 cycles. It detects arc fault who comes from fire start and is constantly analyzing electric settings. It isolates involved circuit automatically before first flame appearance. It is particulary adapted for circuit protection where the fire start is the most important in domestic intallation (outdoors, rooms). It has an ON/OFF and fault trip indication for signalling (local) with toggle control. This product is compatible with comb busbar and distribution block. It has a tunnel type terminal connection at top or bottom. The connection allows rigid copper cables from 1mm² to 16mm². It has a tunnel type terminal connection at top or bottom. The connection allows flexible copper cables from 1mm² to 10mm². The rated operational voltage (Ue) is up to 230VAC with operating frequency of 50Hz, conforming to AS/NZS 61009.1 standard.
