Χαρακτηριστικά:
New Iimp 12.5kA surge arrester.
Special design for saving installation space.
It protect to indirect and direct lightning effect or other transient over voltage
High discharge current.
SPD design according with GB18802.1/IEC61643-1 standard.
Indication window for clear display of SPD status, each pole with one indication window.
Number of poles: 3P+NPE.
Replaceable module.
Optional remote status signaling.
Εφαρμογή:
To prevent power supply equipment from being damaged by surge and lightning.
Use on buildings in applications where there is an external lightning protection system installed, usually installed at the service entrance.
Widely used in the transformer low-voltage side as the first protection of the power supply.
Εγκατάσταση:
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.
