Product details
Basic product parameters
FD series The breakthrough design of shellcircuit breakers lies in the fully enclosed type Contact, which can minimize the size of thedevice to achieve maximum currentlevel division Break.
When the circuit breaker acts, it generates twice the speed and force of a traditional circuit breaker Degree, thus possessing excellentcurent limiting ability. This causes the current in the circuitbreaker to Reduced peak and power values, protected cables, downstreamprotectivecircuit breakers, and installation The electric power and thermal stress of the device decrease
implementing electric power limltation througn backup protection and placing it in the FD seres plastic casing the protecive devicedownstream of the circuit breaker must be able to bear the load generated bythe install-ation base point Thermal efects and electrodynamics The upstream instal-ation of current limiting circuit breakers limits these Numerical value,there-fore, compared to infinite current function molded case circuit breakers, they can be used in a smaller and more compact manner And economic prot-ection devices.
