Why Choose the Mersen S209362 High Voltage DIN Back-up Fuse?
The Mersen S209362 is a high performance Limitor®-PD high voltage DIN back-up fuse designed to protect transformers and associated medium voltage equipment against damaging short-circuit currents. Identified by the catalogue number 45DB360V6,3PD, it provides dependable current-limiting protection for industrial, commercial and utility power distribution systems.
Manufactured using a robust ceramic body, pure silver fuse elements and silver-plated copper end caps, the S209362 is engineered for consistent electrical performance and long-term reliability. As a back-up fuse manufactured in accordance with IEC 60282-1 and VDE 0670 T402, it interrupts substantial fault currents whilst helping reduce thermal and mechanical stress on transformers and switchgear.
Rated at 36 kV AC and 6.3 A, the S209362 has a 56 mm diameter, a 537 mm overall length and an integrated 80 N striker. Its DIN-format cylindrical construction enables installation within compatible high voltage fuse holders and transformer protection assemblies.

High voltage back-up fuses interrupt substantial short-circuit currents before excessive thermal and mechanical forces can damage transformers, cables and associated switchgear. Their current-limiting action reduces the peak fault current and total energy passed into the protected electrical system.
The Mersen S209362 is intended for use within a correctly coordinated medium voltage protection system. Its integrated striker can activate compatible switch-disconnectors or indication mechanisms when the fuse operates, helping isolate the affected circuit and improve installation safety.
Typical Applications
- Medium voltage transformer protection.
- High voltage distribution switchgear.
- Transformer substations.
- Industrial electrical distribution systems.
- Utility power networks.
- Infrastructure and renewable energy installations.
