It combines Type AC residual-current detection at 30 mA with a B-curve overcurrent trip at 13 A, all rated for a 4.5 kA short-circuit breaking capacity. The 1+N-pole width (two modules) occupies 36 mm on the rail. Spring-cage terminals accept 1.5–25 mm² conductors; strip length 10 mm for solid or ferruled stranded. Type AC detection means the device trips on sinusoidal AC residual currents only — suited for circuits supplying resistive, inductive, or electronic loads without pulsed DC components. The 30 mA sensitivity provides personal protection against direct-contact faults. B-curve magnetic release (3–5 In) handles lighting and general-purpose socket circuits without nuisance tripping on inrush.","metaTitle":"Siemens 5SU1353-0KV13 FI/LS protector, Type AC, 30mA, 4.5kA,","metaDescription":"Siemens 5SU1353-0KV13 FI/LS protector, Type AC, 30mA, 4.5kA, 1+N B 13A.
