It is suitable for AC 50/60Hz, TT, TN-S, TN-C, IT and other power supply systems with rated operating voltage 220V/380V, and factory low voltage power and control system, indirect lightning and direct lightning influence or other transient overelectricity. Surge protection is mainly applied to surge protection requirements in residential areas, third industries, mining and industrial enterprises.


Product features


1. built-in overheating and temperature control circuit breaker


2. alarm indicating device, normal (green), red (fault).


3. core components are strictly screened, stable performance and reliable operation.


Use of attention


1. when installing, attention should be paid to cables coming in and out of surge protective devices, so as to avoid the two coupling of surge.
