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.

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.

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.

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.

Unique design

The unique design on breaking whips and dry type breaking chambers eliminates the risk of oil leakage.

Risk of oil eliminated Pollution risk for soil waters

Safety risk in case of failed interruption

No need to check oil level or compensate for possible leakages

Risk of conventional air breaking chambers eliminated by protected breaking contacts Malfunctions due to dust, sand, ice and

small animals

Risk of terrain fires due to arcing
