It integrates Type AC residual-current detection at 30 mA sensitivity with a C-curve overcurrent trip at 10 A, all rated for a 10 kA breaking capacity. ## Deployment context The 70 mm depth (D=70 mm per the description) fits standard DIN-rail enclosures. As a 1+N-pole unit it occupies one module width on the rail, switching the line conductor only while the neutral is switched internally for isolation. This form factor is typical for final-distribution boards in residential, commercial, and light-industrial panels where combined RCD/MCB protection is required in a single module.","metaTitle":"Siemens 5SU1354-1KV10 FI/LS Protector, Type AC, 30mA, 10kA,","metaDescription":"Siemens 5SU1354-1KV10 FI/LS protector, Type AC, 30mA sensitivity, 10kA breaking capacity, 1+N-pole C 10A.
