The 70 mm width (4 module spaces on a standard DIN rail) is wider than a single-pole RCBO — check your enclosure fill factor before committing. Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded; strip length 8 mm avoids whiskers under the cage. The 1+N-pole configuration switches the phase and breaks the neutral through the RCD, so the neutral bar in the board must be broken at this position.","metaTitle":"Siemens 5SU1654-0KV16 FI/LS Protector, 16A B-Curve 10kA 300m","metaDescription":"Siemens 5SU1654-0KV16 FI/LS protector, Type AC, 300mA, 10kA, 1+N-pole B 16A.
