Siemens Sentron 5SU1654-6KV06 FI/LS-Protector Type A (PSE/SSF), D=70mm, IΔn 300mA, 10kA, 1+N-pole B 6A.
D=70 mm width fits standard DIN-rail enclosures.
The Type A designation means it detects pulsating DC fault currents in addition to AC — important for modern loads like variable-speed drives, LED lighting, and medical equipment that generate residual currents a standard Type AC device would miss.
It is a combined residual-current device and miniature circuit breaker (RCBO) for 1+N-pole circuits, providing both earth-fault protection (300 mA, Type A) and overcurrent/short-circuit protection (B curve, 6 A, 10 kA).
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
