Why Choose the Mersen K1000141 High Voltage DIN Back-up Fuse?
The Mersen K1000141 is a premium DIN high voltage back-up fuse designed to provide dependable short-circuit protection for medium voltage transformers operating within electrical distribution systems. As part of the proven Mersen Limitor®-PT series, it incorporates Controlled Power Dissipation (CPD) technology to reduce operating temperatures whilst maintaining outstanding protection performance.
Manufactured in accordance with IEC 60282-1, the K1000141 uses pure silver fuse elements, silver-plated copper end caps and a robust ceramic body to deliver reliable current-limiting protection and long service life. The integrated 80 N thermal striker enables operation with compatible switchgear mechanisms for enhanced transformer protection.
With a rated voltage of 24 kV AC, a 16 A current rating and standard 56 mm × 442 mm DIN dimensions, the Mersen K1000141 is ideally suited to transformer protection in substations, industrial switchgear and medium voltage distribution systems.
