Window indication
The surge protector is provided with a fail-safe device. When the protector breaks down due to overheating, 
the fail-safe detach device can automatically detach from the power grid and give an indication signal.When the protector is normal,the display window will show green, and after failure, the display window will show red.
Alarm remote signaling contacts (TS)
The protector can be with remote signaling contacts. The remote signaling contacts have a set of normally open and normally closed contacts. When the protector is working normally, normally closed contacts are connected.
If one or more modules of the protector fail, the contact will change from normally open to normally closed. Normally open contacts will work and send trouble information.This is an optional feature, not a standard feature.
