This Resi9 product is a residual current breaker with overcurrent protection (RCBO). It is a 1P+N circuit breaker with 1 protected pole, 20A rated current (In) at 30°C conforming to AS/NZS 61009.1 standard and the C tripping curve. The earth leakage protection class is type A with a sensitivity of 30mA. The earth-leakage protection time delay is an instantaneous. The breaking capacity (Icn) is up to 6000A at 230VAC with operating frequency of 50Hz to 60Hz. This product protects against short circuit, cable overload, electrical shock by indirect contact and fire hazards. It brings safety, reliable solution for commercial and industrial applications with high breaking capacity. This product is compatible with comb busbar and distribution block.
