Product details

It protects branch circuits against overload and short-circuit in 230/400 V AC networks, breaking up to 6000 A at those voltages per IEC 60898-1.

Rated current 40 A at 230/400 V AC — this is the continuous load the MCB carries without tripping. The 6000 A breaking capacity (Icn) at 230/400 V AC means it can safely interrupt a fault current up to 6 kA; this is the standard domestic and light-commercial level per IEC 60898-1. Electrical durability is 10,000 cycles under load — adequate for normal switching duty in a distribution board. Mechanical durability matches at 10,000 cycles.

Frequently asked questions

Where can I buy DOM11381 and how is it quoted?

The DOM11381 is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time, not from a live stock count.

What is the breaking capacity of DOM11381?

The breaking capacity is 6000 A at 230/400 V AC, 50/60 Hz, conforming to IEC 60898-1.

What is the difference between DOM11381 and a current Domae 40A C-curve MCB?

The DOM11381 is an obsolete order code. A current-production Domae 40 A 1P C-curve MCB shares the same DIN-rail footprint, 18 mm width, and basic ratings, but the exact breaking capacity, terminal size, and curve tolerance should be verified against the original design before substitution.
