Varning

Drift av elektriska apparater och utrustningar medför att

vissa delar av utrustningen stár under farlig spänning.

Montering, underhåll, ändringar eller ombyggnader av

effektbrytare får därför bara utföras av kvalificerad personal

och under iakttagande av gällande säkerhetsföreskrifter.

Säkerställ innan skenanslutningsplintarna monteras att

alla ledare, anslutningsdetaljer och plintar är spänningslösa.

Enbart de medföljande skruvarna får användas för fastsätt-

ning av skenanslutningsplintarna.

Försummelse kan medföra dödsfall, svåra kroppsskador

eller svåra anläggningsskador.

Avviso di pericolo

Durante il funzionamento, alcune parti dell' apparecchio

elettrico si trovano inevitabilmente sotto tensione pericolosa.

Il montaggio, la manutenzione, la sostituzione e

l'equipaggiamento dell'interruttore devono essere eseguiti

da personale qualificato osservando le norme di sicurezza.

Prima di montare i morsetti per le sbarre collecttrici

bisogna assicuarsi che tutti i conduttori, componenti

d'allaciamento e morsetti siano privi di tensione.

Per il fissaggio dei morsetti per le sbarre collectrici vanno

impiegate esclusivamente le viti fornite.

La non osservanza di tali norme può causare la morte,

gravi lesioni alle persone o ingenti danni materiali.

letzungen oder erheblicher Sachschaden die Folge sein.

Warning

Hazardous voltage are present on specific parts in this

electrical device during operation.

Only qualified personnel, paying attention to the relevant

safety precautions, should install, maintain, modify or fit

accessories to the circuit-breakers.

Before fitting the bus connector terminals, ensure that all

conductors, connection components and terminals are in

dead state.

Only the screws supplied may be used to fix the bus

connector terminals.

Non-observance of this warning can result in death,

severe personal injury or substantial property damage.

Advertencia

Cuando se emplean aparatos eléctricos, es inevitable

que piezas de los mismos se encuentren bajo tensiones

peligrosas.

Por tanto, el montaje, el mantenimiento, los modificaciones

y los complementos con accesorios de los interruptores

de potencia solamente deben ser efectuados por personal

calificado, tomando en cuenta las medidas de seguridad

correspondientes.

Antes de montar los bornes para barras, es indispensable

comprobar que el interruptor se encuentre en la posición

"Desconectado" y que todos los conductores, piezas de

conexión y bornes se encuentren libres de tensión.

Para fijar los bornes para barras solamente se deben

emplear los tornillos incluidos en el suministro.

Si esto no se respeta, la consecuencia puede ser muerte,

heridas graves o daños materiales considerables.

Attention

Le fonctionnement d'un appareillage électrique implique

nécessairement la présence de tensions dangereuses sur

certaines de ses parties.

Le montage, l'entretien, et toutes modifications des

disjoncteur ne doivent être effectués que par du personnel

qualifié en respectant les règles de sécurité correspondantes.

Avant de procéder au montage des bornes pour barres,

vérifier que tous les conducteurs, tous les éléments de

raccordement et toutes les bornes sont hors tension.

Les bornes pour barres ne doivent être fixées qu'a à l'aide

des vis de fixation jointes.

La non-application des mesures de sécurité peut entraîner

la mort, des lésions corporelles graves ou des dégâts

matériels importants.

Do you have a question about the Siemens 3VF 5 and is the answer not in the manual?

This document describes the Siemens 3VF 5 bus connector terminals, also referred to as "Schieneanschlußklemmen für 3VF 5" in German, "Bornes pour barres pour 3VF5" in French, "Bornes para baras para 3VF5" in Spanish, "Morsetti per sbarre collectrici per 3VF5" in Italian, and "Skenanslutningsplinten för 3VF5" in Swedish. The specific model numbers covered are 3VF9524-1JB10 and 3VF9524-1JB20.

Function Description:

The Siemens 3VF 5 bus connector terminals are designed to provide a secure and reliable electrical connection for busbars within low-voltage switchgear applications. These terminals facilitate the connection of conductors to the busbar system, ensuring proper current distribution and system integrity. The device is an essential component for power distribution, allowing for the integration of various electrical circuits into a common busbar structure. The design appears to support multiple busbar configurations, as indicated by the different current ratings and corresponding busbar dimensions.

Important Technical Specifications:

The document provides key technical specifications related to the current ratings and compatible busbar dimensions for the 3VF9524-1JB10 and 3VF9524-1JB20 models:

Model 3VF9524-1JB10 / 3VF9524-1JB20:
- For a rated current (Ie) of 200 A, the compatible busbar dimensions are 4 x 20 x 1.
- For a rated current (Ie) of 250 A, the compatible busbar dimensions are 5 x 20 x 1.
- For a rated current (Ie) of 315 A, the compatible busbar dimensions are 6 x 20 x 1.
- For a rated current (Ie) of 400 A, the compatible busbar dimensions are 10 x 20 x 1.
Maximum Current: The overall maximum current capacity is indicated as 250 A.
Short-Circuit Current (Icc): The maximum short-circuit current is specified as 65 kA.
Torque Settings:
- The main fastening screws (item 4 in the diagram) require a torque of 20 ± 2 Nm.
- The smaller fastening screws (item 8 in the diagram) require a torque of 3 ± 0.3 Nm.

Usage Features:

The bus connector terminals are designed for integration into low-voltage switchgear. The installation process involves securing the terminals to the busbar using the provided screws. The diagram illustrates the assembly sequence, showing the placement of the terminal body, busbar, and various fastening components.

Components: The assembly includes the main terminal body (implied by the overall structure), fastening screws (items 4 and 8), washers (item 6), and a busbar (item 7). Item 9 appears to be a cover or protective element.
Installation Procedure: The installation involves positioning the busbar within the terminal, followed by the insertion and tightening of the screws to the specified torque values. The use of only the supplied screws is explicitly mandated for proper and safe fastening.
Safety Precautions: The document emphasizes critical safety warnings in multiple languages:
- Qualified Personnel: Installation, maintenance, modification, and fitting of accessories must only be performed by qualified personnel who adhere to relevant safety precautions.
- De-energized State: Before mounting the bus connector terminals, it is crucial to ensure that all conductors, connection components, and terminals are in a dead (de-energized) state.
- Supplied Screws: Only the screws provided with the product should be used for fastening the bus connector terminals.
- Consequences of Non-Compliance: Failure to observe these warnings can lead to death, severe personal injury, or substantial property damage.

Maintenance Features:

While the document does not explicitly detail specific maintenance procedures, it highlights the importance of maintenance being carried out by qualified personnel. This implies that any inspection, retightening, or replacement of components should follow established safety protocols and be performed by individuals with the necessary expertise in electrical systems. The specified torque values for the screws are critical for maintaining a secure connection, and periodic checks of these connections might be part of a broader maintenance schedule for the switchgear. The robust design, indicated by the high short-circuit current rating, suggests a durable component that, once correctly installed, should require minimal routine maintenance beyond general system checks.
