Why Choose the Mersen H1000116 High-Voltage Fuse?
The Mersen H1000116, catalogue number 45DB360V4P, is a high-voltage DIN back-up fuse-link designed to provide dependable protection for medium-voltage transformers against damaging short-circuit currents. As part of the proven Mersen Limitor®-P range, it delivers reliable current-limiting performance for high-voltage switchgear, transformer feeders and electrical distribution systems.
Rated at 36 kV AC and 4 A, the H1000116 rapidly interrupts severe fault currents, helping to reduce thermal and mechanical stress on transformers, cables, busbars and associated switchgear. Its robust construction ensures long-term reliability in demanding industrial and utility applications.
Manufactured with a durable ceramic body, pure silver fuse elements and silver-coated copper end caps, the fuse incorporates a standard 80 N striker for operation of compatible switchgear mechanisms or fuse indication. The DIN-format fuse measures approximately 56 mm in diameter and 537 mm in length.
