Model

MJ8-POE-C6A
Brand / Made in

CITEL / FRANCE

POE++ compatible
Gigabit Ethernet (Cat.6A)
Shielded enclosure and connectors
2 kA discharge capability
UL497B certified
IEC 61643-21, EN 61643-21 compliance

The MJ8-POE-C6A is designed to protect sensitive data-processing equipment connected to a POE++ (Power over Ethernet) network from transient overvoltages. This SPD is qualified with the maximum transmission speed and cabling category used for these Ethernet networks: 10Gigabit Ethernet and Category 6A. Obviously, it is applicable for the Ethernet networks with lower categories.

The MJ8-POE-C6A surge protector is deployed in signal network applications with data transmission speeds up to 10 GMbps. The surge protector is housed in a shielded enclosure with high quality RJ45 shielded jacks. The transient protection circuit is based on high energy gas discharge tubes (GDT) and a network of fast response silicon avalanche diodes (SAD) to achieve sharp clamping of very large surge events.

INSTALLATION
The surge protector for IT networks must be installed while respecting the following principles:

SPDs must be installed on the both sides of the transmission line (e.g. server side and terminal equipment side)
The surge protector and the protected equipment must be interconnected with the bonding network of the installation.
The earthing conductor (between the earth output of the SPD and the bonding circuit of the installation) must be as short as possible (less than 0.50 m).
The AC power supply of the equipment must also be surge protected.
