GENERAL INFORMATION
Ref. 12095130 device is a varistor protection against overvoltage for power supply line (SPD). In case of overvoltage
generated by atmospheric events, the device operates in order to limit risk of damage to system electric and
electronic equipment.
The led on the upper side of the device indicates that surge protection is working properly.
When the led turns off, the protection must be replaced.
The led stays on also in case of mains failure.
Designed and certified according to EN61643-11/A11 European standard.
The device is not subject to FOLLOW CURRENT condition, so in case of maintenance operations there are few
chances of service interruption for the protected device.
It is suggested to add to SPD class III device a mains filter (for ex. Ref. 12095125) for high frequency noise. In this way,
the protection against EMC conducted noise is completed.
For connections to the system, see the manual and the specific safety rules for electric installation.
INSTALLATION
The device must be fixed to a DIN bar in a closed service panel.
