Les systèmes de sectionneurs sous charge développés par Altınsoy Enerji sont conçus pour assurer des opérations d’ouverture et de fermeture de circuit sûres, rapides et entièrement contrôlées dans les infrastructures de distribution d’énergie. Notre gamme de produits est largement utilisée dans les systèmes de moyenne et basse tension (MT/BT), des installations industrielles et centrales de production aux postes compacts et aux applications modulaires sur panneaux. Grâce à leur haute capacité de coupure, à leurs matériaux isolants avancés et à leur grande durabilité mécanique, nos sectionneurs garantissent une interruption énergétique sûre, même en conditions de surcharge ou de court-circuit.
Les sectionneurs sous charge d’Altınsoy Enerji sont fabriqués en pleine conformité avec les normes TS EN 60947-3 et IEC 60947-3, et leurs performances sont vérifiées grâce à des tests type réalisés avec succès dans des laboratoires accrédités. Chaque modèle offre des avantages techniques clés, tels que résistance élevée à la température, structure ignifuge sans halogène (classe V0), corps compact et faibles besoins de maintenance.
Grâce à leur mécanisme interne avancé, nos sectionneurs sous charge offrent un contrôle indépendant sécurisé, quel que soit le mouvement de l’opérateur lors des opérations de commutation instantanée, améliorant ainsi à la fois la sécurité de l’opérateur et la continuité du système. Nos sectionneurs sous charge verticaux, horizontaux et à fusible répondent aux exigences des infrastructures énergétiques modernes avec des caractéristiques telles que grande distance d’isolation, coupure indépendante phase par phase, options d’intégration de transformateurs de courant et compatibilité totale avec les systèmes de panneaux compacts.

Load Break Switches Disconnectors
- Vertical Fused Load Disconnectors
Vertical Fused Load Disconnectors are designed for the safe, controlled, and uninterrupted management of power flow in medium-voltage systems. In three-phase AC circuits, they safely disconnect the rated current and protect the system against both overload and short-circuit conditions.
NH fuses, which enable safe disconnection under load, stand out with their fast response time against short-circuit currents. Compared to thermal-magnetic circuit breakers, they interrupt the circuit in a much shorter time, eliminating the risks of deformation and physical injury that may occur due to high short-circuit currents. With a 100 kA breaking capacity, they provide high-level protection while also offering a cost-effective solution.
- Compact Design – Maximum Efficiency
Our Vertical Fused Load Disconnectors are manufactured with options for both independent phase operation and simultaneous opening/closing of all three phases. The desired rated current or operating class can be easily adjusted by replacing the NH knife-type fuses.
All our products are manufactured in full compliance with the TS EN 60947-3 standard and provide long-term operational safety.
Thanks to the compact enclosure design developed by Altınsoy Engineering and the optional current transformer (CT) integration, these disconnectors occupy minimum space inside panels. This offers both easy installation and the advantage of detailed phase-by-phase measurement capability.
- Smart Protection – Fast Response
In short-circuit or overload conditions, only the faulty line is disconnected while the remaining parts of the facility continue operating without interruption. This feature plays a critical role in operational continuity, maintenance efficiency, and overall energy performance.
Each product successfully passes type tests conducted in accredited test laboratories, ensuring long-term operational reliability certified by international standards.
Altınsoy Vertical Fused Load Disconnectors are not only protection devices but also critical safety components that guarantee energy continuity. Every unit is subjected to strict quality control processes and combines precision-engineered metal components with high thermal stability insulation materials.
Wherever safety, efficiency, and continuity are priorities in energy infrastructures, the Altınsoy signature carries power into the future.
