Product Introduction

DZ47Z-125H series DC miniature circuit breakers are mainly used for photovoltaic, generator and other lines with rated DC voltage of 100V-1000V, and can also be used for battery lines with DC voltage of 36-150V, as overload and short circuit protection of DC lines and infrequent line conversion. The maximum working current of the circuit breaker is 150A. The circuit breaker consists of a plastic shell, an operating mechanism, a contact arc extinguishing system, a tripping mechanism, etc. The non-polar design allows the upper and lower wiring to be swapped without affecting the protection performance. The interior uses red copper (red copper) as the main conductor, and composite silver contacts are used to extend the service life of the tripping structure. The unique arc extinguishing system design ensures efficient DC arc extinguishing. The shell is made of highly flame-retardant and high-strength special plastics, which are resistant to high voltage, corrosion, strong impact resistance and light weight.

This product complies with GB10963.2 and IEC60947-2 standards.
