It saves a module width over separate devices and eliminates the wiring between them. The Type AC detection handles sinusoidal AC earth faults; the 30 mA trip threshold covers personnel protection (additional protection per IEC 60364). The B-curve 6 A thermal-magnetic side clears overcurrents on resistive or light inductive loads — lighting circuits, small control transformers, socket outlets in commercial or residential sub-distribution. The 1+N-pole format switches the line conductor and opens the neutral; the neutral pole is not a switched pole in the overcurrent sense but provides isolation. The 70 mm depth (D=70MM) is the installed depth from the DIN-rail front face — check enclosure depth clearance if retrofitting into a shallow box.","metaTitle":"Siemens 5SU1353-0KV06 FI/LS Protector, Type AC, 30mA, 6A B-C","metaDescription":"Siemens 5SU1353-0KV06 FI/LS protector, Type AC, 30mA sensitivity, 4.5kA breaking capacity, 1+N-pole B-curve 6A.
