JSC cabinet counterDetailed product description：

When the requirements for overvoltage monitoring are not high for JSC type cabinet counters, JSC cabinet counters can also be simplified to record the number of relative ground discharges.
The JSC cabinet counter is designed with no residual voltage, and the sampling end is installed on the grounding phase of the three-phase combination product. The display end is external and can be directly mounted on the panel of the complete switchgear.

This product has a low price, simple structure, and high practicality.
The protective device is equipped with a counter, which is indicated by the letter "J" after its standard model.
For example, FGB-10B-J indicates the installation of JSC counters on FGB products.
