Why Choose the Mersen D099915 Medium-Voltage Fuse?
The Mersen D099915 is a high-performance medium-voltage cylindrical fuse-link designed to provide dependable protection for transformers, switchgear and specialised medium-voltage distribution equipment. Identified by the product designation 25500 CP GLC 20.340 0,5, this fuse features a 0.5 A rated current and is engineered for low-current protection applications where precise fault interruption is essential.
Manufactured by Mersen, the D099915 uses advanced current-limiting technology to interrupt short-circuit currents rapidly before damaging thermal and mechanical stresses can develop. This helps protect valuable electrical assets while improving system reliability and reducing maintenance requirements.
Its robust 20 × 340 mm cylindrical construction makes it suitable for installation in compatible medium-voltage fuse carriers and switch-fuse assemblies. The fuse is widely used for voltage transformer protection, auxiliary transformer circuits and specialised medium-voltage control applications requiring dependable low-current protection.
