Why Choose the Mersen G1000115 High-Voltage Back-Up Fuse?
The Mersen G1000115, catalogue reference 45DB360V2P, is a high-voltage DIN back-up fuse-link designed to protect distribution transformers against the damaging effects of short-circuit currents. As part of the Mersen Limitor®-P series, it provides reliable transformer protection for medium-voltage switchgear, substations and power distribution systems.
Rated at 36 kV AC and 2 A, the G1000115 is manufactured using a ceramic fuse body with pure silver fuse elements and silver-plated copper end caps to deliver excellent electrical performance and long service life. It is manufactured in accordance with IEC 60282-1 and the VDE T4 specification for transformer protection fuse-links.
The fuse incorporates an integrated 80 N striker for operation indication and activation of compatible switchgear mechanisms. With a 31.5 kA breaking capacity, it rapidly interrupts severe fault currents before damage can occur to transformers and associated equipment.
