The 70 mm module width fits standard DIN-rail distribution boards. Type A detection means the device trips on sinusoidal AC residual currents and on pulsed DC residual currents up to 6 mA — the minimum needed for single-phase rectifier loads like switched-mode power supplies, LED drivers, and variable-speed drives on the line side. The 300 mA IΔn is a fire-protection threshold, not a personnel-protection threshold (30 mA is the touch-safe level); this unit is sized for circuits where the primary concern is cable insulation degradation or slow-developing earth faults, not direct human contact. ## Deployment context Snap-on DIN-rail mounting for 70 mm of panel width. The 1+N-pole arrangement switches the line conductor only; the neutral is switched internally for disconnection but not overcurrent-protected. Intended for single-phase final subcircuits in commercial or industrial distribution boards where Type A residual-current protection is specified by local wiring rules (PSE/SSF).","metaTitle":"Siemens 5SU1654-7KV13 FI/LS Protector Type A, 13A C, 300mA,","metaDescription":"Siemens 5SU1654-7KV13 FI/LS protector, Type A (PSE/SSF), 1+N-pole, C-curve 13A, 300mA IΔn, 10kA breaking capacity.
