Note
To integrate the circuit breaker optimally into the control panel, the 4-pole circuit breaker can
optionally be ordered with the neutral pole on the right or left-hand side of the circuit breaker.
These are basic versions of the circuit breaker and are permanently dened in the circuit breaker.
In all these versions, the circuit breaker is capable of full performance (no derating, full current
carrying capacity, and protection settings).
Phase sequence neutral left: N - L1 - L2 - L3
Phase sequence neutral right: L1 - L2 - L3 - N
The phase sequence L1, L2, L3 can be subsequently changed (to L3, L2, L1) by the user in the
electronic trip units of the 6-series to match any system conguration.
Mounting options
In addition to oor mounting, both the xed-mounted breaker and the withdrawable breaker
permit direct rear wall mounting.
For oor mounting of the xed-mounted breaker version, mounting supports are required
(see Section Support for oor xation (xed breaker) (Page123)).
