Application
|
| |
NSX Series moulded case circuit breaker is one of new type breakers which our company adopts international advanced design, manufacture technology to develop. The rated insulating voltage is 950V. Suitable for AC 50Hz (60Hz). Rated
working voltage 690V or below, rated working current is 12.5A to 630A of circuit and used in distributing electric energy. Non-frequent making and breaking in the normal conditions and protecting when circuit and installation are overload,
short circuit and lacking voltage. Rated shell-rack and the breaker whose current is under 400A, take protection effect when mouse cage motor's non-frequent start, breaking off working and protecting form overload, short circuit and lacking voltage. The product conforms to GB14048.2, IEC 60947-2 standards.
