Crossarm installationOne of the most common building standards where the line switchdisconnector is integrated on the same crossarm as the lines.

Wooden poles are most often used for this type of installation.

Installation below live lineSome building styles and standards require a separate crossarmbelow the line crossarm.

Sufficient clearances to the pole and between phases can bearranged by the flexible arrangement of phase elements.

Installation above live lineA typical installation example above the live lineon a steel structure pole.

Vertical installationUsed for branching lines down to cables.The vertically installed switch disconnector is also usedas a transformer switch disconnector.

Two pole mountingAll above 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

NPS for Transformer Switch Disconnector/NPF fuse holder


The NPS switch disconnector can be equipped with several types offuse holders. The vertically mounted NPS can be used as transformerswitch disconnector. The breaking capacity of the whip (25/50 A) isenough for disconnecting a fully loaded distribution transformer up to800/1600 kVA.

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.

NPS can be equipped with integrated earthing contact for openand earthed position.

The separate fuse holder for HRC and SMIA-KR_ can also be equippedwith surge arresters for one-,two-, or three-phase installation.

NPS can be equipped with a separate fuse holder for DIN-type fuses(CEF outdoor HRC fuses).

Feeder Automation solutions forair insulated switch disconnectors

Our disconnector terminal units [DTU’s] are designed for remote controland local automation applications of NPS switch disconnectors and othersimilar types with up/down operating movement.

Together with REC 501 or REC 523 monitoring and control units both simpleapplications such as remote open/close operations and more sophisticatedauto sectionalizing schemes and measurements can be realized.

Standard communication protocols available for

� ANSI X3.28 HD only with REC 501

� RP570 only with REC 501

� IEC 60870-101, unbalanced

� MODBUS ASCII & RTU format

� DNP 3.0

Analog inputs available for standard CT’s and VT’s.

DTU’s can also be used without integrated motor mechanism.These can be used in applications such as master terminal for monitoringand controlling existing motor devices for indoor and outdoor switchdisconnectors and other motor operated apparatus.It is also applicable for switching devices with an integratedactuator.

One terminal with REC 523 can control up to 4 slave units

Unique design

The unique design on breaking whips and dry type breakingchambers 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 byprotected breaking contacts

� Malfunctions due to dust, sand, ice and small animals

� Risk of terrain fires due to arcing

The exceptionally high number of making operations[>50 times 8 kA] enables use to locate faulty line sections byoperating against the fault.
