Siemens 5SU1356-1DA20 FI/LS protector, Type AC, 20A C-curve, 30mA residual sensitivity, 6kA breaking capacity, 1+N-pole, pigtail connection.
The Siemens 5SU1356-1DA20 is an FI/LS combination unit — an RCD and MCB in one DIN-rail module — rated 20A C-curve with 30mA residual current sensitivity and 6kA breaking capacity.
The 70 mm depth (D=70MM) and pigtail connection make it a direct swap for existing Siemens FI/LS units in standard distribution boards. The 1+N-pole configuration protects one live conductor and switches the neutral; the pigtail simplifies wiring in pre-assembled panel layouts where busbar access is tight.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
It is an FI/LS combination protector (RCD + MCB) for 20A, 30mA residual sensitivity, 6kA breaking capacity, Type AC — used in final subcircuits requiring both overcurrent and earth leakage protection in a single DIN-rail module.
