RMU1 series surge protectorDetailed product description：

The lightning current is large, the residual voltage is low, and the response time is less than 25 nanoseconds.
Built in failure disengagement device, when the surge protector fails due to overheating or breakdown, the failure disengagement device can automatically disconnect it from the power grid without affecting the normal operation of the system.
Visual alarm indicator device, green is normal, red is invalid.
Adopting a plug-in structure, the protection module can be replaced without power outage. And adopt the internationally recognized TH35 standard installation rail.
FS remote signaling device can be selected according to user needs to send fault signals when one or more modules of the surge protector fail, achieving remote monitoring.
