Circuit breaker 3VA2 IEC Frame 250 — breaking capacity class E
The trip unit provides LSI protection: overload protection (Ir) adjustable from 100 A to 250 A, short-time short-circuit protection (Isd) from 0.6 to 10× In, and instantaneous protection (Ii) from 1.5 to 10× In. This range lets the integrator tune selectivity with downstream breakers while maintaining arc-flash energy reduction targets.
The product class is C: manufactured/produced to order, not a stocked catalog item. This means each unit is built against a specific order, so lead time and availability are confirmed at quote time rather than from a shelf count.
