If the fault level at the panelboard exceeds 6 kA, step up to the 10 kA rated siblings in the same SENTRON family. It also carries a DC rating of 72 V maximum — useful for DC sub-circuits in control panels, though the C-curve's magnetic trip responds differently on DC, so verify coordination with the DC load's inrush profile.
Snap-on DIN-rail mounting in any position. Accepts supplementary devices (shunt trip, auxiliary contacts, alarm switch) — the product extension is installable, so you can add remote tripping or status indication without replacing the breaker. Sealable terminals are standard, which satisfies utility meter-seal requirements in many jurisdictions. Halogen-free and silicon-free construction — no corrosive off-gassing under fault, which matters when the breaker shares an enclosure with sensitive electronics or silver contacts.
For high-cycle switching applications (daily disconnect under load), consider a contactor instead.
