VT-63 Miniature Circuit Breaker
The workhorse DIN-rail MCB for residential and light-commercial boards. Repeatable trip curve, padlockable toggle, 6 kA and 10 kA breaking options.
VT-63H High-Breaking MCB
10 kA high-breaking variant for denser commercial risers. Same footprint as VT-63 so panel layouts stay unchanged.
Miniature Circuit Breakers
DIN-rail MCB family tooled in Liushi for residential and light-commercial boards. 1P–4P, 1–63 A, 6 kA and 10 kA, B/C/D curves.
Which IEC file covers the MCB family?
Type tests follow IEC 60898-1. The 10 kA variant also references IEC 60947-2. Reports travel with the first article, not only a CE mark on the carton.
Can we keep the same footprint when we step from 6 kA to 10 kA?
Yes. VT-63H uses the same DIN-rail pitch as VT-63 so a panel drawing does not have to be redrawn.
