It's designed for 230/240 V AC single-phase circuits at 50/60 Hz. The 30 mA residual sensitivity covers basic personnel protection against direct contact. Supply can enter from either top or bottom; the design is instantaneous (non-time-delayed) Type AC, meaning it trips on sinusoidal AC residual currents without intentional delay. Halogen-free and silicon-free construction. Overvoltage category III, pollution degree 2, surge voltage resistance 4 000 V.","metaTitle":"Siemens 5SU9356-1CR40 SENTRON RCBO, 40 A, 30 mA, Type AC, C-","metaDescription":"Siemens SENTRON 5SU9356-1CR40 RCBO, 1P+N, 40 A, 30 mA, Type AC, C-curve, 6 kA per EN 60898, 10 kA per IEC 60947-2.
