The Siemens 5SU1353-0KV10 is a Type AC FI/LS-protector (RCBO) combining overcurrent and residual current protection in a single 1+N-pole module.
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.
