the poles and the auxiliary parts are located.
Each pole, isolated from the others, contains the breaking parts and the current transformer of its own
phase.
The circuit-breaker is available in two types:
• fixed version
• withdrawable
The circuit-breaker in fixed version (see Figure 67) has its own terminals for connection to the power
circuit.
The withdrawable circuit breaker consists of a mobile part (see Figure 68) and of a fixed part (see Figure
69 for IEC and Figure 70 for UL) for connection through its own terminals to the power circuit.
The coupling between the mobile part and the fixed part is via disconnection contacts mounted on the
fixed part.
