Summary

DDX1 series of short-circuit current limiter products cleverly

exploit explosive cutting technology, current-limiting fuse

technology, high voltage insulation technology and electrical 

measurement and control technology to give product the

capability of both large current conduction and super-strong 

fault breaking. It makes the product an ultra-high-speed switch

that can limit short-circuit current in the first half wave. Main 

functions: protect the main equipment of electrical system,

protect power grid safety, saving energy and reduce

consumption, optimize system structure and the operation 

mode, improve power quality and power supply reliability, etc.



Rated voltage:0.4kV-40.5kV

Rated current:630A-6300A

Rated short circuit breaking capacity:Achievable 200kA

The total breaking duration:<10ms

Current limiting coefficient:15%-50%



首半波短路电流限制器   Products with higher rated voltage and higher rated 

current can be specially customized according to the 

users' requirements.
