Connection terminal for circular conductors (copper/aluminum)
Circular conductor terminals for the incoming supply and outgoing feeders consist of an
aluminum body with tin plating to prevent oxidation. Both aluminum and copper cables may
be used. Only one conductor is permitted per terminal.
The circular conductor terminals are available for the VL160X to VL400 molded case circuit
breakers.
For additional information, refer to the technical data in the chapter Configuration of main
connections (Page 136).
Auxiliary conductor terminal
The 3VL offers two versions of auxiliary conductors for voltage tap.
A) Connection with lug to circular conductor terminal (voltage tap)
The 3VL1-3VL7 circular conductor terminals are provided with an M3 hole. Using the screw
with contact washer provided, cable lugs up to 2.5 mm² can be connected.
The maximum load of the auxiliary conductor connection I
max
= 500 mA must not be
exceeded.
