It delivers Type AC residual current detection at 30 mA, combined with a B-curve overcurrent trip at 32 A, all rated for a 10 kA breaking capacity. The 30 mA trip threshold means it protects against direct-contact faults in circuits supplying socket outlets or general-purpose loads, not just fire-prevention earth leakage. The 1+N-pole form factor occupies a single module width, so it fits retrofit into existing consumer units or sub-distribution panels without re-spacing. The Type AC detection handles sinusoidal AC residual currents — the most common domestic fault waveform — but does not cover pulsating DC or smooth DC faults. For circuits with variable-speed drives, LED lighting, or EV chargers, a Type A or Type F device would be needed instead.","metaTitle":"5SU1354-0KV32 Siemens FI/LS Protector, Type AC, 30mA, 10kA,","metaDescription":"Siemens 5SU1354-0KV32 FI/LS protector, Type AC, 30mA, 10kA, 1+N-pole B 32A, D=70mm.
