It belongs to the Basic Devices family within the Siemens 5SL6 series of MCBs. The 1+N-pole configuration switches both line and neutral, with overcurrent protection on the line pole only. That's standard for single-phase final subcircuits where you want the neutral switched for isolation but don't need to protect it thermally. ## Lifecycle and compliance — active, RoHS, REACH RoHS compliance is confirmed since June 2013. REACH Article 33 duty-to-inform documentation is available per the current candidate list. Export control classifications are AL: N / ECCN: N — no license required for most destinations. Product class B means this is a return-restricted item — Siemens requires direct partner contact for returns. Not a showstopper, but worth noting if your procurement process expects blanket return rights. Snap-on DIN rail mounting, standard 18 mm per pole width. The 1+N unit occupies two modules (36 mm) on the rail. Wire termination accepts copper conductors up to 25 mm² for the line and load terminals — busbar-compatible for grouped distribution. The C-curve 40 A rating is a common choice for general-purpose socket circuits, lighting banks, and small resistive or mixed loads in commercial and residential final distribution boards.","metaTitle":"Siemens 5SL6540-7CC Miniature Circuit Breaker, 40A C-Curve 1","metaDescription":"Siemens 5SL6540-7CC miniature circuit breaker, 230V, 6kA, 1+N-pole, C-curve, 40A.
