It carries a Type AC residual-current sensitivity of 30 mA and a C-characteristic overcurrent trip at 25 A, with a 6 kA short-circuit breaking capacity. The 70 mm depth fits standard DIN-rail distribution boards. Type AC detection means the device trips on sinusoidal AC residual currents only — the standard choice for circuits without non-sinusoidal or pulsating DC fault profiles (e.g., basic lighting, resistive heating, socket outlets in residential or light commercial panels). The 30 mA sensitivity provides personal protection against direct-contact faults. The C-curve (25 A) handles moderate inrush from motorized loads like small pumps or compressors up to roughly 5.5 kW at 230 V.","metaTitle":"Siemens 5SU1356-1KV25 FI/LS Protector, Type AC, 30mA, 6kA, 1","metaDescription":"Siemens 5SU1356-1KV25 FI/LS protector, Type AC, 30mA, 6kA, 1+N-pole, C 25A.
