Why Choose the Mersen S1032946 High Voltage DIN Back-up Fuse?
The Mersen S1032946 is a premium Limitor®-PTS high voltage DIN back-up fuse engineered to provide reliable protection for medium voltage transformers and associated switchgear against damaging short-circuit currents. Manufactured to IEC 60282-1 and VDE T402 requirements, it incorporates Mersen's advanced low power dissipation technology together with an integrated 80 N thermal striker for enhanced operational safety and reliability.
Designed for use within both air-insulated and gas-insulated switchgear, the Limitor®-PTS range uses pure silver fuse elements, silver-plated copper terminals and a robust ceramic body to deliver dependable fault interruption whilst minimising heat generation inside the fuse compartment. These features help extend equipment life and improve system reliability.
Rated at 12 kV AC with a 16 A current rating, the S1032946 features a compact 56 mm diameter and 292 mm length, making it suitable for transformer protection within compact medium voltage switchgear used throughout industrial facilities, substations and utility networks.
