The 1+N-pole format (switched phase plus switched neutral) fits a 70 mm deep enclosure — standard for flush-mount consumer units and small distribution boards. The neutral pole opens and closes with the phase, so no separate neutral bar connection is needed downstream of the device. Spring-cage terminals accept 0.75–25 mm² conductors; strip length 8–10 mm avoids whiskers under the clamp.","metaTitle":"Siemens 5SU1654-6KV40 FI/LS Protector Type A, 40A B-Curve 30","metaDescription":"Siemens 5SU1654-6KV40 FI/LS-protector Type A, 40A B-curve, 300mA residual, 10kA breaking capacity.
