It protects a 1+N-POL circuit (single-phase with neutral) at a C-curve 32 A overcurrent rating and a 300 mA residual current trip threshold, Type AC (sensitive to sinusoidal AC fault currents only). Breaking capacity is 4.5 kA. The D=70 mm dimension refers to the overall depth of the device, which matters when fitting into shallow enclosures or gland-plate clearance. ## Deployment context Snap-on DIN-rail mounting for panel integration. The 1+N-POL form factor occupies a single module width on the rail. The 300 mA sensitivity is a higher threshold than the standard 30 mA for personal protection; this unit is typically selected for equipment or fire protection rather than direct personnel shock protection.","metaTitle":"Siemens 5SU1653-1KV32 FI/LS Protector, Type AC, 32A C-curve,","metaDescription":"Siemens 5SU1653-1KV32 FI/LS protector Type AC, 1+N-POL, C 32A, 300mA sensitivity, 4.5kA breaking capacity.
