To prevent secondary damage, transformers have to be protected against thermal and dynamical overload caused by short circuit currents.
JEAN MÜLLER high-voltage high rupturing capacity fuse-links have particularly been designed for this application.
The standardized fuse characteristicsare coordinated with other protective devices.
Consequently,there is no need for complex short-circuit calculations.
JEAN MÜLLER IKUS II HV HRC fuse-links are designed according the international standard IEC/EN 60282–1 and national standard DIN VDE 0670–402.
