The 30 mA Type AC residual-current element catches sinusoidal AC earth faults — the standard choice for general-purpose socket circuits and lighting where no DC fault content is expected. ## Panel-fit details Two modular-width units (36 mm wide) snap onto standard DIN rail. Halogen-free and silicon-free construction, which matters for clean-room or sensitive-environment specs.","metaTitle":"Siemens 5SU9356-1KK32 SENTRON RCBO, 32A C-Curve, 30mA Type A","metaDescription":"Siemens 5SU9356-1KK32 SENTRON RCBO, 1P+N, 32A C-curve, 30mA Type AC residual current, 6kA per EN 60898.
