Mersen J1005269 FT7 high voltage current-limiting fuse-link rated at 36 kV AC and 6.3 A for transformer circuits and medium voltage electrical equipment.
The Mersen J1005269 is a specialised FT7 high voltage fuse-link designed to provide dependable protection for voltage transformers, control power transformers and associated medium voltage equipment. Identified by the manufacturer reference TP360V6,3A325, it is suitable for electrical systems operating at up to 36 kV AC.
This current-limiting fuse is engineered to interrupt damaging fault currents rapidly, helping protect transformer windings and connected equipment from excessive thermal and mechanical stress. Its compact cylindrical construction enables installation in compatible fuse clips or medium voltage switchgear assemblies where space-efficient transformer protection is required.
With a rated current of 6.3 A and a rated voltage of 36 kV AC, the Mersen J1005269 is intended for specialist medium voltage applications. Its robust fuse-link construction supports reliable operation in utility substations, industrial switchgear and power distribution installations.
High voltage current-limiting fuses protect transformer circuits by interrupting excessive current before it can cause severe damage to windings, insulation and associated switchgear. By limiting the peak current and energy passed during a fault, the fuse helps reduce stress on valuable medium voltage equipment.
The Mersen J1005269 is particularly suited to transformer circuits that require a compact fuse-link with a low current rating and high operating voltage. Correct fuse selection should always account for transformer inrush current, system voltage, coordination requirements and the specifications of the associated fuse holder.
