Why Choose the Mersen A1032953 High-Voltage Transformer Fuse?
The Mersen A1032953, catalogue number 45DB240V16PTS, is a premium DIN high-voltage back-up fuse engineered for transformer protection in medium-voltage electrical systems. As part of the advanced Mersen Limitor®-PTS series, it combines low power dissipation with an integrated 80 N thermal striker, making it ideal for modern air-insulated and gas-insulated switchgear.
Designed using pure silver fuse elements, silver-plated copper terminals and a robust ceramic body, the A1032953 delivers dependable protection against damaging short-circuit currents while minimising thermal losses during normal operation. Its innovative thermal striker helps prevent overheating within the fuse compartment, enhancing safety and extending equipment service life.
With a rated voltage of 24 kV AC, a rated current of 16 A and a 65 kA breaking capacity, this fuse is ideally suited for protecting distribution transformers in industrial plants, utilities and compact substations. The Limitor®-PTS range is also recommended for compatible gas-insulated switchgear from manufacturers including Siemens and Ormazabal.
