Features:
Iimp: 7kA
Visual display.
Precise and easy to install.
It is the combination of Class B (10/350us) and class C (8/20 us ), used at the equipotential connection of LPZ 0 and LPZ 2 zone.
Application:
It is generally use in electrical industry.
Installation:
Wiring according to the mark of surge protector according to the wiring diagram.
When installed according to the installation diagram shows the connection, where l (L1, L2, L3) for the line, n is neutral, PE ground wire, do not mistake. After the installation is complete, check that the protection unit is plugging in place, close the automatic circuit breaker (fuse) switch, check the working status is normal.
Protector in use during the fault display window should periodically verify and view state when red fault display window or remote Terminal outputs alarm signals, the protector fails, should be repaired or replaced in a timely manner.
