Why Choose the Mersen Z1000292 High-Voltage Transformer Fuse?
The Mersen Z1000292, catalogue reference 45DB360V40PTD, is a high-performance DIN high-voltage back-up fuse-link designed to protect power transformers against the thermal and dynamic effects of severe short-circuit currents. It belongs to the Mersen Limitor®-PTD series, which combines reliable current limitation with controlled power dissipation for demanding medium-voltage protection systems.
Rated at 36 kV AC and 40 A, the Z1000292 provides a maximum breaking capacity of 36 kA. Its current-limiting operation reduces the magnitude and duration of fault currents, helping protect transformers, switchgear and connected distribution equipment from potentially damaging electrical and mechanical stress.
The fuse-link features an integrated 80 N thermal striker that provides positive operation indication and can actuate compatible switchgear tripping mechanisms. Pure silver fuse elements, silver-plated copper terminals and a durable ceramic body provide dependable electrical, thermal and dielectric performance in air or gas insulated switchgear installations.

Reliable Protection for High-Voltage Transformers
The Mersen Z1000292 interrupts high short-circuit currents before they can cause significant damage to transformer windings, electrical connections and associated switchgear. By limiting the peak current and fault energy, the fuse helps minimise thermal deterioration and electrodynamic forces throughout the protected installation.
As a back-up fuse-link, the Z1000292 should be coordinated with suitable protection equipment for overloads and lower-level fault currents. Correct selection should consider transformer power, operating voltage, magnetising inrush current, minimum interrupting current and the characteristics of associated switchgear.
Typical Applications
- High-voltage power transformer protection.
- Air insulated switchgear installations.
- Gas insulated switchgear systems.
- Utility substations and distribution networks.
- Industrial high-voltage power systems.
- Transformer feeder panels and compact substations.
