NB1Z-63 AC/DC miniature circuit breaker is suitable for AC 50/60Hz rated voltage of 230/400V V.
To 63A line, or DC voltage 220V, rated DC current to 63A line for overload and short circuit protection
Under normal circumstances, it can be used as the infrequent operation conversion of the line, and can
also be used as a disconnected line to isolate the line and equipment maintenance
Use of switches.
Circuit breakers are suitable for industrial, commercial, high-rise and civil residences and other places.

design feature
High rated short circuit breaking capacity.
Dual wiring function, the outlet can be conveniently connected with standard bus bar and soft and hard wires.
With red and green safety indication, the safety is higher.
With the operation of energy storage mechanism, the contact is closed quickly, which overcomes the problem of
manual operation of the handle
The adverse effect of speed greatly prolongs the service life of products.
The connecting terminal has dovetail with anti-misoperation function, which improves the connection efficiency and reliability.
Products can be used with a variety of modular accessories, such as S9, V9, XF9, XF9J.
Plastic parts such as shells are made of high flame retardant, high temperature resistant and impact resistant plastics.
Installation method:
Adopt TH35-7.5 section steel mounting rail for installation.
With isolation function, it can be used as an isolation switch when disconnecting the line for line and equipment maintenance.
