Features
● T2/T1+T2 surge protection has two types of protection, which can can meet Class I (10/350 μS waveform) and Class II (8/20 μS waveform) SPD test, and voltage protection level Up ≤ 1.5kV;
● Modular, large-capacity SPD, maximum discharge current Imax=40kA;
● Pluggable module;
● Based on zinc oxide technology, it has no power frequency aftercurrent and fast response speed, up to 25ns;
● The green window indicates normal, and the red indicates a defect, and the module needs to be replaced;
● Dual thermal disconnection device provides more reliable protection;
● Remote signal contacts are optional;
● Its surge protection range can be from power system to terminal equipment;
● It is applicable to direct lightning protection and surge protection of DC systems such as PV combiner box and PV distribution cabinet.

Failure release device, Alarm release device
Failure release device
The surge protective device is equipped with a failure protection device. When the protector is broken down due to overheating, the failure protection device can automatically disconnect it from the power grid and give an indication signal.
The window displays green when the protector is normal, and red when the protector fails.
Alarm remote signaling device
The protector can be made into a variety with remote signaling contacts. The remote signaling contacts have a set of normally open and normally closed contacts. When the protector works normally, the normally closed contacts are connected. If one or more modules of the protector fail, the contact will change from normally open to normally closed, and the normally open contact will work and send a fault message.
