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.","metaTitle":"Siemens 5SU1356-1DA20 FI/LS Protector, 20A, 30mA, 6kA","metaDescription":"Siemens 5SU1356-1DA20 FI/LS protector, Type AC, 20A C-curve, 30mA, 6kA, 1+N pole, pigtail.
