Novaris has introduced an EC90 version of the RJ45 network protection products.
This particular unit is designed for installation in the field end of a Shielded Twisted Pair cable run to protect the external equipment.
The standard variants of the RJ45 protectors connect the shield directly to earth through the DIN rail on the product for a low impedance connection to earth. To prevent current flow onto the shield of the cable there can only be one connection to earth. For this reason the field protection device has to be isolated from the local earth.
The RJ45 EC90 products achieve this using a non conductive DIN rail mount and a Gas Discharge tube between the product and the earth connection provided through the flying lead. During normal operation the unit remains isolated, but during a surge this GDT fires for the duration of the overvoltage and allows the current to pass to earth.
The EC90 version are available for both our single device gigabit protectors in the Cat6 and PoE variants.
