Product details

The Siemens 5SU1656-1KV06 is a combined residual-current device and miniature circuit breaker — an FI/LS protector — in a single 1+N-pole module. Type AC (WS) responds to sinusoidal AC residual currents only. The 300 mA threshold suits protection against fire risk from earth faults.

DIN-rail integration note

The 70 mm width occupies four standard 17.5 mm DIN-rail module spaces. Snap it onto a top-hat rail (EN 60715) in a distribution board or sub-distribution enclosure. The 1+N-pole design — switching both phase and neutral — means it fits directly into single-phase final circuits without a separate neutral bar takeoff.

Frequently asked questions

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What does the description FI/LS-PROTECTOR TYPE AC (WS), D=70MM IFN 300MA, 6KA, 1+N-POLE C 6A mean for selection?

It is a combined RCD/MCB: Type AC residual detection at 300 mA (fire protection), C-curve overcurrent trip at 6 A (moderate inrush loads), 6 kA breaking capacity, 1+N poles, 70 mm wide.
