It is rated B-curve 25A for overcurrent, with a residual sensitivity of 30mA (Type AC) and a breaking capacity of 6kA. The 70mm width and pigtail connection suit standard distribution board layouts where space is allocated per DIN rail module count. The B-curve 25A rating means the unit trips magnetically at 3 to 5 times rated current (75–125A) — appropriate for resistive and general-purpose loads, but not for high-inrush motor circuits where a C- or D-curve would be needed.","metaTitle":"Siemens 5SU1356-0DA25 FI/LS Protector, 25A, 30mA, 6kA, Type","metaDescription":"Siemens 5SU1356-0DA25 FI/LS protector, Type AC, 25A B-curve, 30mA sensitivity, 6kA breaking capacity.
