Its fixed overload protection is set at Ir = 63 A, and the fixed short-circuit protection trips at Ii = 10 × In — meaning it holds through motor inrush and clears a hard fault fast. The N conductor is unprotected (no integral overload or short-circuit element on the neutral pole), and the breaker ships with clamp-type terminals for field wiring.
Integration notes
The clamp terminals accept copper or aluminum conductors within the rated cross-section range — verify lug compatibility for your wire size. The two auxiliary switches are pre-wired to the breaker's internal mechanism; no separate mounting or wiring of add-on blocks is required.
