• Bridging of current transformer output without
changing the connection of the secondary, so
to avoid any output overvoltage during either
the maintenance or the installation procedure
(see figur
• Easy output and earth connection (see fig. 2).
• Screw terminals compatible with any kind of wire
terminals (see figur
