Circuit-Breakers and Switch-Disconnectors up to 1600A

Circuit-breakers or switch-disconnectors – Moeller gives you the choice

All the frame sizes in NZM circuit-breaker and P/NZM switch-disconnector versions are available. Compared to the P switch-disconnector, the NZM switch-disconnector offers the additional option of remote tripping via a voltage release.

Within a given frame size, the accessories for circuit-breakers and switch-disconnectors are identical.

The advantages are clear – with only one basic unit and standard accessories:

Engineering is easy.
Storage is less complicated.
Operation is safer.
Fitting takes less time.

Four-pole switching

The four-pole NZM is used wherever standards also require switching of the N conductor. Four-pole circuit-breakers and switch-disconnectors are available in every frame size.

Main switch and isolating characteristics

In all versions the circuit-breakers and switch-disconnectors conform to IEC/EN 60947, with lockable actuation they also conform to IEC/EN 60204-1 and VDE 0113 Part 1.
