The 4-module-width (72 mm) body snaps onto DIN rail and accepts solid conductors up to 25 mm², making it a direct fit for new or replacement 4-pole subfeeds. The C-curve (magnetic trip between 5× and 10× In) means this breaker handles moderate inrush from motor starters and small transformers without nuisance tripping — typical for mixed lighting and socket-outlet circuits in a 400 V three-phase panel. The 6 kA SCCR at 400 V per EN 60898 is the standard domestic/commercial interrupting rating; if your upstream fault current exceeds that, you need a current-limiting upstream device or a higher-rated breaker (e.g., 10 kA class). ## Integration notes for the panel builder Depth is 76 mm, installation depth 70 mm — leaves 6 mm clearance behind the rail for wiring. The 72 mm width (4 modular units) occupies four 18 mm slots. Pollution degree 2, overvoltage category III — standard for fixed-installation downstream of the main panel.","metaTitle":"Siemens SENTRON 5SN6416-7CN MCB, 4P, 16A, C-Curve, 6kA","metaDescription":"Siemens SENTRON 5SN6416-7CN miniature circuit breaker, 4-pole, 16A, C-curve, 400V AC, 6kA breaking capacity per EN 60898.
