It packs both overcurrent and residual current protection into a single 70 mm wide unit, saving a DIN-rail slot over separate devices. ## Protection profile Type A detects pulsating DC and AC sinusoidal residual currents. The 300 mA trip threshold suits sub-distribution circuits. The thermal-magnetic overcurrent side is C-curve, rated 32 A. ## Panel fit At 70 mm wide (4 module spaces), it replaces a separate RCBO or an RCD + MCB pair at the same footprint. The 1+N-pole format switches the line and monitors the neutral — no neutral bar needed downstream for the RCD function.","metaTitle":"Siemens 5SU1654-7KV32 FI/LS Protector Type A, 32A C, 300mA,","metaDescription":"Siemens 5SU1654-7KV32 FI/LS protector, Type A (PSE/SSF), 1+N-pole, C-curve 32A, 300mA IΔN, 10kA breaking capacity.
