Why Choose the Mersen Z1032952 High-Voltage Transformer Fuse?
The Mersen Z1032952, catalogue reference 45DB240V10PTS, is a premium DIN high-voltage back-up fuse-link designed to provide dependable protection for medium-voltage power transformers. As part of the advanced Mersen Limitor®-PTS series, it features low power dissipation and an integrated thermal striker, making it ideal for air and gas insulated switchgear applications where reliability and thermal performance are essential.
Rated at 24 kV AC and 10 A, the Z1032952 offers an impressive 65 kA breaking capacity. Its advanced current-limiting characteristics minimise the thermal and dynamic effects of short-circuit currents, helping to protect transformers, switchgear and associated electrical infrastructure.
Manufactured using a ceramic body, pure silver fuse elements and silver-plated copper terminals, this fuse-link incorporates an 80 N thermal striker that provides positive indication of fuse operation while helping prevent overheating within the fuse compartment. Siemens and Ormazabal recommend the Limitor®-PTS range for use in compatible gas insulated switchgear.
