Discription :
Used in power supply & distribution line for overload & short circuit protection , also can be used for line non-frequent on-off operation and conversion. Specialized in communication and PV direct current (DC)system.
-
Discription :
Mainly used in distribution lines of AC 50HZ, rated working voltage 230V, rated current not more than 40A. For overload & short circuit protection, also can be used for line non-frequent on-off operation and conversion. The breaking ability can reach 6kA.
-
Discription :
It is mainly used for overload, short circuit protection in AC 50Hz, Rated operating voltage 230V, rated current 40A and below distribution line, and It can also be used for line non-frequent on-off operation and conversion.The breaking ability can reach 4.5kA.
-
Discription :
Mainly used in distribution lines of AC 50HZ, rated working voltage 230/400V, rated current not more than 63A. For overload & short circuit protection, also can be used for line non-frequent on-off operation and conversion, and It can also be used for conversion of infrequent operation between lines under normal conditions.The breaking ability can reach 12kA.
-
Discription :
A breaking capacity of 12kA up to 32A and 10kA between 40 to 63A.
Current-limiting scheme: in the event of a short circuit, are able to limit the let-through current to 60%-70% of the rated current. The trip mechanism ensures perfect closure every time,thereby considerably improving the performance of these devices and extending their average lifetime.
