We use ACB in LT and VCB in HT.But if we use VCB in LT and
ACB in HT that what will be the effect on the system or any
power range?
Answer Posted / jithin
VCB is designed for HT it has vaccum chamber that prevents arcing and it triping speed is higher
ACB is desined for LT the terminals are almost open to atmospere it can cause flashing if we use it on HT
