Application scope
The LT-G series surge protective device belongs to the DC power lightning protection of class II T2 PV system. When the system is overvoltage due to lightning or other reasons, the protector will rapidly take action in the nanosecond time, and the overvoltage will be leaded into the earth , so as to protect the equipment on the grid.
Product features
1. Needn’t consider the load current, plugable, It can be replaced without cutting off power, easy to maintain;
2. built-in temperature control circuit breaker, high safety performance, no continuous flow;
3. the indicator window green is normal, red indicates failure, prompt replacement, clear and easy to argue;
4. The Remote Control interface (terminal point) is used to realize the remote monitoring work state.
5. Y type design, three groups of high performance MOV, more efficient and safer.
