Vertical fuse-disconnectors provide safe disconnection of rated currents under load, protection against overload currents and short circuits in 3-phase alternating current circuits, in accordance with the utilization category and the operating voltage. NH fuses, which can safely interrupt the current, can be easily removed and replaced. The reaction time to short-circuit current is much faster than that of thermal magnetic circuit breakers, so there are no serious deformations causing injuries at the moment of short-circuit interruption; the breaking capacity is 100kA, which is quite high. Their cost is much lower than that of thermal magnetic circuit breakers.
Vertical fuse-disconnectors; The three phases can be switched on and off separately or together, they can be used at the desired rated current or operating class by changing the knife-blade fuses depending on the change of the drawn current and the load. The technical characteristics and dimensions of the products comply with the TS EN 60947-3 standard.
It is very important in terms of safety, efficiency and economy of operation to prevent faults caused by short circuits or excessive currents in electrical installations; in the event of any fault, only the faulty part is disabled while the other parts of the plant continue to operate, and at the same time the fault can be easily repaired.
Our Altınsoy brand vertical fuse-disconnectors stand out with the feature of integrating a current transformer into a single body size and therefore with the advantage of taking up minimal space on the boards and performing detailed measurements from all outputs; at the same time they have successfully passed all type tests carried out in accredited laboratories and proven their high reliability.
