It's rated at 400 V AC, 50 Hz, and carries a 6 kA breaking capacity per EN 60898 alongside a 30 kA rating per IEC 60947-2 — the higher figure governs industrial panel coordination where fault current levels are known and selectivity matters.
Four poles let this breaker switch all three phases plus neutral in a single unit — common for three-phase loads where neutral isolation is required, like distribution sub-feeds or multi-circuit panels. The C-curve (implied by class and peer context) trips at 5–10× rated current, suited for motor and transformer inrush without nuisance opening. The 30 kA IEC 60947-2 rating is the number that matters for industrial panel SCCR compliance. The 6 kA EN 60898 figure applies to residential or light commercial installations where the prospective fault current is lower. At 72 mm wide and 4 modular width units, this breaker occupies four 18 mm slots on a DIN rail. Panel space is tight — that's 18 mm more than a 3-pole unit, so verify the rail length and adjacent device clearance before committing the layout.
Snap-on DIN rail mounting (standard for the 5SN series) means it clips directly onto a 35 mm rail inside a distribution board or control panel.
