The 70 mm width (D=70mm) occupies four standard 17.5 mm DIN-rail module spaces — factor that into your enclosure fill when replacing a separate RCD and MCB combo that might take less total width. The 1+N-pole format switches the line conductor and disconnects the neutral, but the neutral pole is not switched on the overcurrent side; it opens only on residual fault.","metaTitle":"Siemens 5SU1653-1KV06 FI/LS Protector, Type AC, 6A C, 300mA,","metaDescription":"Siemens 5SU1653-1KV06 FI/LS protector, Type AC, 6A C-curve, 300mA, 4.5kA, 1+N-pole.
