Product Introduction
DZ47Z-63X/125 DC miniature circuit breaker series is mainly used in DC lines with rated voltage up to 1000V and rated working current up to 63A, for overload and short circuit protection of DC lines and infrequent conversion of lines. The circuit breaker is composed of a plastic casing, an operating mechanism, a contact arc extinguishing system, and a tripping mechanism. The shell is made of high flame-retardant, high-strength special plastic, which has strong impact resistance and light weight.
This product complies with GB10963.2 and IEC60947-2 standards.
