The 5SU1353-0KV10 carries a lifecycle stage of current, meaning Siemens continues to manufacture and support this order code as a standard catalogue item. The B 10A trip curve means the magnetic release operates between 3 and 5 times rated current (30–50 A), suited for resistive and light inductive loads like lighting circuits or general-purpose socket outlets. The 1+N-pole format switches the line conductor only; the neutral is solidly connected through. ## Deployment context Snap-on DIN-rail mounting for 70 mm deep distribution boards. The Type AC designation limits this RCBO to standard AC residual current applications — not suitable for three-phase rectifier loads or circuits with electronic ballasts where pulsed DC leakage may occur.","metaTitle":"Siemens 5SU1353-0KV10 FI/LS Protector, Type AC, 30mA, 4.5kA,","metaDescription":"Siemens 5SU1353-0KV10 FI/LS-protector, Type AC (WS), 30mA, 4.5kA, 1+N-pole, B 10A.
