That 70 mm depth (D=70MM) keeps the assembly compact on the DIN rail, which matters when you're squeezing multiple circuits into a tight residential or light-commercial load center. The 30 mA IΔn is the standard sensitivity for socket-outlet circuits in most domestic and commercial installations — it catches the leakage a person might draw through a hand-to-ground fault before the heart goes into fibrillation. The B characteristic (B 40) means the magnetic trip fires at 3 to 5 times rated current (120–200 A), which suits resistive and general-purpose loads — lighting, heaters, socket outlets — where inrush isn't heavy. The G-type designation points to a specific Siemens variant within the 5SU1 family, likely differing in the neutral-switching arrangement or terminal design from the standard F-type.","metaTitle":"Siemens 5SU1354-0LV40 FI/LS Protector, 30mA, 10kA, B 40A","metaDescription":"Siemens 5SU1354-0LV40 FI/LS protector, Type AC, 30mA, 10kA, 1+N-pole B 40A.
