Rated breaking capacity is 4.5kA. The 70mm width (D=70mm) means it takes up two standard modular DIN-rail slots in a consumer unit or distribution board. The 300mA sensitivity is a fire-protection level, not personnel protection (30mA would be required for that).","metaTitle":"Siemens 5SU1653-0KV25 FI/LS-Protector, Type AC, 25A B-curve,","metaDescription":"Siemens 5SU1653-0KV25 FI/LS-Protector Type AC (WS), 1+N-POL B 25A, 300mA, 4.5kA.
