1) Other Cu bar sizes possible, but the total Cu cross section must not be less.
2) Aluminium bars - please enquire.
ATTENTION
On 4-pole circuit-breakers, the neutral conductor must
always be connected all on the left (front view).
Otherwise this can cause malfunctions of the electronic
overcurrent release.
Connection of cables directly on the circuit-breaker
connections is not permissible.
