Siemens 5SU1656-0KV13 FI/LS protector, Type AC (WS), 1+N-pole, B-curve 13A, 300mA residual sensitivity, 6kA breaking capacity, 70mm width.
The 300 mA sensitivity (IFN) is typical for fire-protection or whole-floor circuits rather than personal shock protection (which calls for 30 mA).
The 70 mm width (D=70MM) occupies 4 standard DIN-rail modules (each 17.5 mm). The 1+N-pole construction switches the line conductor and disconnects the neutral; the neutral pole is not switched in all RCBOs, so verify your distribution board's neutral bar arrangement — this unit expects the neutral to pass through the device.
It is rated at 6 kA breaking capacity with 300 mA residual sensitivity (IFN), Type AC, B-curve 13 A, 1+N-pole.
This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
