The Siemens 5SL4605-7CC is a 3+N-pole miniature circuit breaker from the SENTRON 5SL series, rated at 400 V with a 10 kA breaking capacity and a C-trip curve at 0.5 A. This is the part you spec when you need a 0.5 A C-curve MCB in a 3+N configuration — common for protecting a three-phase control transformer or a small lighting circuit where each pole plus neutral is switched.
Snap-on DIN rail mount, standard 1 MW per pole width. The 3+N-pole form factor occupies four modular spaces. Wire termination accepts 0.2–2.5 mm² solid or stranded copper, strip length 8 mm. Spring-cage terminals on the 5SL family hold well under vibration — no screw retorque needed.
RoHS compliant since 01-06-13. REACH Article 33 applies — the part contains lead (CAS 7439-92-1) above the 0.1% threshold, so a duty-to-inform notice is required if it goes into a product sold into the EU. Export control is straightforward: AL N / ECCN N, no license required.
