Type AC (WS) responds to sinusoidal AC residual currents only. The 300 mA threshold suits protection against fire risk from earth faults. ## DIN-rail integration note The 70 mm width occupies four standard 17.5 mm DIN-rail module spaces. Snap it onto a top-hat rail (EN 60715) in a distribution board or sub-distribution enclosure. The 1+N-pole design — switching both phase and neutral — means it fits directly into single-phase final circuits without a separate neutral bar takeoff.","metaTitle":"Siemens 5SU1656-1KV06 FI/LS Protector, Type AC 6A 300mA 6kA","metaDescription":"Siemens 5SU1656-1KV06 FI/LS protector, Type AC (WS), 6A C-curve, 300mA residual, 6kA breaking capacity.
