The 1+N-pole construction switches and protects the line conductor only; the neutral is switched but not monitored for overcurrent. The 70 mm width (4 module spaces) is standard for a 1+N RCBO in the Siemens 5SU series, so it occupies four 17.5 mm DIN-rail positions in the enclosure.","metaTitle":"Siemens 5SU1653-6KV20 FI/LS Protector Type A, 20A B-Curve 30","metaDescription":"Siemens 5SU1653-6KV20 FI/LS protector Type A (PSE/SSF), 20A B-curve, 300mA residual, 4.5kA breaking capacity, 1+N-pole.
