The word nominal means the lowest possible safe amount. So, nominal current or nominal voltage is the lowest amount necessary to perform an electrical function like keeping a light turned on.
The original answer is incorrect. 'Nominal' simply means 'named'. So a 'nominal voltage' is the 'named voltage', as opposed to an 'actual voltage'. For example, the nominal voltage of residential supplies in the UK is 230 V; however, this value is allowed to vary between +10/-6% of the nominal voltage. In other words, a nominal voltage of 230 V may vary between 216 V and 253 V.

Can i use a circuit breaker with 420V nominal voltage in 520V line voltage nominal current of circuit breaker is 1600A if I can how much current can pass from this circuit breaker?

NO! NO! NO!. The circuit breaker must be rated for the line voltage used. Exceeding this limit can cause catastrophic failure!. If you are really working on a 1600A bus, sto
