Emax E4.2 circuit-breakers consist of a steel structure which houses the operating mechanism, the poles
and the auxiliary parts.
Each pole, insulated from the others, contains the breaking parts.
It is available in two types:
• fixed version
• withdrawable
The fixed version circuit-breaker has its own terminals for connection to the power circuit (Figure 17).
The withdrawable version consists of a movable part (Figure 18) and by a fixed part for connection to the
power circuit by its own terminals (Figure 19).
The moving and fixed parts are coupled together by special clamps installed on the movable part.
