NBSe BN60 DC 1P 250V Series Circuit Breaker,dc circuit breaker
1. Applications
BN60-63Z series photovoltaic DC miniature circuit breaker is suitable for overload, short circuit protection and Infrequent conversion link of DC transmission, distribution
system facilities and electrical equipment in the line, with rated current below 63 and DC rated voltage of 125V, 220V,440V,550V,750V and 1000V.
With super-class current limiting performance, it can accurately protect relay protection and automatic devices from overload and short circuit. The small DC circuit breaker BN60-63Z has the advantages of current limiting and arc extinguishing capability. After a large number of comprehensive scientific experiments,It can realize full
selective protection between main (sub) screen, protective screen
and relay screen in DC system below 3000Ah.
2. Usage:
a. DC Power Supply system, Communication power, EPS,UPS
b. Rail transit and electric locomotives;
c. Marine system.
