40kA Type 2 Class C AC Surge Protection Device.
Our offered surge protector is designed by utilizing the top grade material and the most advanced techniques.
Reliable control thanks to Thermo Dynamic Control disconnector.
Application:
For protection of consumer equipment against transient voltage caused by indirect lightning strike and switching operations.
Use in domestic, commercial and light industrial installations.
Usually installed in household power distribution boards, telecom machinery center, computer equipment center, elevator control center, hospital’s surgery and ICU, information equipment, electronic equipment and in front of control equipment or nearest socket box of control equipment.
Installation:
Usually installed in the distribution box office, the power phase line (L), neutral (N), respectively, corresponding surge protectors access terminals to ensure secure and reliable, and the surge protector ground terminal and ground as well electrical connection.
It should regularly check the work, such as the window turns red indicating the deterioration of its front open space, when the fuse is tripped, timely maintenance or replacement module.
After the installation is complete, check that the protection unit is plug in place, close the automatic circuit breaker (fuse) switch, check the working status is normal.
