The C-curve (6 A) trips between 5 and 10 times rated current – 30 to 60 A – making it suitable for motor and inductive loads that draw a brief inrush. The 300 mA residual sensitivity (Type A) catches pulsating DC fault currents common on single-phase electronics and variable-speed drives. ## Where it goes – panel integration Snaps onto DIN rail in a consumer unit or distribution board. The 1+N-pole format switches the line and switches the neutral pole as well, so it fits sub-distribution circuits requiring both overcurrent and earth-fault protection in a single device. The 70 mm width takes two standard 17.5 mm module spaces plus a bit – plan the enclosure layout accordingly.","metaTitle":"Siemens 5SU1656-7KV06 FI/LS Protector, Type A, 6A C, 300mA,","metaDescription":"Siemens 5SU1656-7KV06 FI/LS protector combines RCD (Type A, 300mA) and MCB (C-curve, 6A, 6kA) in one 1+N module.
