The 5SL6402-7CC: The C-curve means it trips between 5 and 10 times rated current (10–20 A for this 2 A unit), making it suitable for general-purpose branch-circuit protection where moderate inrush from small motors or lighting ballasts is expected. This MCB is a 4-pole device (3 phases + neutral switched) in a single modular housing — standard DIN-rail mount, 4 modules wide. The neutral pole switches and protects, not just isolates, which matters for TN and TT systems where the neutral carries fault current.
Compliance and distribution
