The B-curve characteristic trips at 3–5× rated current, protecting wiring and loads against short-circuit and overload in residential or light commercial final circuits. Rated at 40 A with a 30 mA residual sensitivity, this unit protects a single-phase circuit up to 40 A while providing personal protection against earth faults. The D=70 mm width (4 module spaces) fits standard DIN-rail enclosures; the pig-tail neutral connection simplifies wiring in pre-assembled consumer units.","metaTitle":"Siemens 5SU1356-0DA40 FI/LS protector, Type AC, 40A, 30mA, 6","metaDescription":"Siemens 5SU1356-0DA40 FI/LS protector Type AC, 1+N-pole, B curve 40A, 30mA sensitivity, 6kA breaking capacity.
