Caratteristiche:
Surge arrester for low-voltage power supply system protection against surges.
SPD is suitable for AC 50/60HZ, TT power supply systems.
Protective device adopts 35mm Din rail type mounting.
Designed according to IEC61643-11 and GB18802.1 standards.
As the protector normal works that the pilot lamp is green.
Applicazione:
Widely suitable for TT system, for protecting the buildings.
Installazione:
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.
