4. NPS as a Line Switch Disconnector

5. Crossarm installation
One of the most common building standards where the line switch disconnector is integrated on the same crossarm as the lines.
Wooden poles are most often used for this type of installation.

6. Installation below live line
Some building styles and standards require a separate crossarm below the line crossarm.
Sufficient clearances to the pole and between phases can be arranged by the flexible arrangement of phase elements.

7. Installation above live line
A typical installation example above the live line on a steel structure pole.

8. Vertical installation
Used for branching lines down to cables.
The vertically installed switch disconnector is also used as a transformer switch disconnector.

9. Two pole mounting
All installation examples are also available for two-pole mounting.
Pole fitting accessories for various pole types are also available
wooden poles
concrete poles
steel poles and structures

10. NPS for Transformer Switch Disconnector/ NPF fuse holder

11. Fuse holders
The NPS switch disconnector can be equipped with several types of fuse holders.
The vertically mounted NPS can be used as transformer switch disconnector.
The breaking capacity of the whip (25/50 A) is enough for disconnecting a fully loaded distribution transformer up to 800/1600 kVA.
NPS24B1-J2 and NPAC5

12. Fuse holders
If the pole element is horizontally mounted the fuse holder for HRC fuses (6.3, 16, 25 A) or (SMIA-KR_) melting fuses can be easily integrated (up to 63 A) to the switch disconnector.
The fuses are replaced using isolated rods from ground level.
