Its Type AC detection means it trips on sinusoidal AC residual currents only; the 10 mA IΔN sensitivity catches leakage paths that a 30 mA device would pass, making it the right call for circuits where a lower touch-current threshold is specified (e.g., wet locations or circuits supplying hand-held equipment). The 10 mA IΔN is the key differentiator here. Most general-purpose RCDs are 30 mA; a 10 mA unit is specified where the installation standard demands a lower residual operating current — think circuits feeding outdoor sockets, showers, or equipment in medical rooms where the touch-voltage risk is tighter. The C-curve (6 A) means the magnetic trip operates at 5 to 10 times rated current, so it holds through the starting surge of a 1.5 kW motor or a bank of LED drivers without dropping the circuit. ## Panel integration The 1+N-pole format — one switched phase plus a switched neutral — fits standard single-phase consumer units and distribution boards. The 70 mm depth (D=70 mm) is the overall body depth from the DIN-rail mounting surface to the front of the toggle; check the enclosure depth before committing, especially in shallow flush-mount boards where cable bending space is tight. The device snaps onto a 35 mm DIN rail per EN 60715 and occupies a single modular width (18 mm per pole, so 2 modules for the 1+N configuration).","metaTitle":"Siemens 5SU1153-1KV06 FI/LS Protector, Type AC, 10mA, 6A C-C","metaDescription":"Siemens 5SU1153-1KV06 FI/LS protector, Type AC, 10mA IΔN, 4.5kA, 1+N-pole, C-curve 6A.
