The 70 mm depth suits standard DIN-rail enclosures; the Type AC designation means it detects sinusoidal AC earth faults only, not pulsed DC or smooth DC — a selection point for circuits with non-linear loads.","metaTitle":"Siemens 5SU1356-0KV25 FI/LS Protector, Type AC, 30mA, 6kA, 1","metaDescription":"Siemens 5SU1356-0KV25 FI/LS protector, Type AC, 30mA sensitivity, 6kA breaking capacity, 1+N-pole B-curve 25A.
