Rated IP20 once the distribution board is installed and conductors are connected; that's fine for enclosed panels but not for wet environments. The 30 mA residual current sensitivity provides supplementary protection against electric shock for AC sinusoidal fault currents (Type AC). Neutral conductor is not switched by this variant, so the neutral bar stays continuous through the device. Touch protection is built in.","metaTitle":"Siemens 5SU9306-1KK40 SENTRON RCBO, 40A, 30mA, Type AC, C-cu","metaDescription":"Siemens 5SU9306-1KK40 SENTRON RCD-operated circuit breaker. 40A rated current, 30mA residual fault, Type AC, C-curve, 6kA breaking capacity. 1P+N, 18mm wide.
