FAQ
Are NH fuse links included in the switch rating?
No. The switch disconnector and fuse links are separate components with separate selection data.
What sizes are published?
The manufacturer lists NH000, NH00, NH1, NH2 and NH3, plus a size 00 busbar reference.
Is a 60 mm busbar version listed?
Yes. Reference 335040 is listed for an NH00 busbar configuration.
