Why Choose the Mersen Z1000108 High-Voltage Transformer Fuse?
The Mersen Z1000108, catalogue reference 45DB120V200P, is a high-voltage DIN back-up fuse-link engineered to protect distribution transformers against the damaging effects of short-circuit currents. As part of the proven Mersen Limitor®-P series, it delivers dependable current-limiting protection for high-voltage switchgear, controlgear and electrical distribution systems.
Rated at 12 kV AC and 200 A, the Z1000108 rapidly interrupts severe fault currents before they reach their maximum prospective peak. This reduces thermal, electrical and mechanical stress on transformers, cables and associated high-voltage equipment while improving overall system reliability.
Manufactured using a robust ceramic body, pure silver fuse elements and silver-plated copper terminals, the fuse-link measures 88 mm in diameter and 292 mm in length. It incorporates an integrated 80 N standard striker for operating compatible switchgear mechanisms or providing fuse-operation indication.
