Type AC detection means the device responds to sinusoidal AC residual currents — the standard for general-purpose circuits without electronic loads. The C-curve (5–10× In magnetic release) avoids nuisance trips on the starting current of small motors, pumps, or capacitor banks — a B-curve would trip earlier, a D-curve would let more inrush through but is typically reserved for transformer or welding loads.","metaTitle":"Siemens 5SU1354-1KV25 RCBO Type AC, 30mA, 10kA, 1+N C 25A","metaDescription":"Siemens 5SU1354-1KV25 FI/LS protector, Type AC, 30mA IΔn, 10kA breaking capacity, 1+N-pole C-curve 25A.
