Why Choose the Mersen S086795 High-Speed Cylindrical Fuse?
The Mersen S086795 is a high-performance Protistor® cylindrical semiconductor fuse-link designed specifically for rapid and reliable protection in high-voltage DC electrical systems. Rated at 40 A and 1000 V DC, it provides fast, full-range protection for auxiliary circuits, control systems, measuring devices and monitoring equipment.
Part of the Mersen 20 × 127 mm gR fuse range, the S086795 features a gRC design classification and excellent current-limiting characteristics. Its rapid response helps minimise the thermal and electrical energy passed through to sensitive semiconductor components during overload and short-circuit conditions.
The fuse incorporates an integrated striker indicator, allowing compatible fuse monitoring equipment or microswitches to identify when the fuse has operated. Its robust cylindrical construction, high interrupting capability and dependable cycling performance make it suitable for industrial automation, renewable energy, power conversion and DC distribution applications.

Reliable Protection for High-Voltage DC Circuits
High-speed gR fuse-links are engineered to interrupt overload and short-circuit currents before damaging levels of thermal energy reach semiconductor devices and associated electrical equipment. Their fast response and low let-through energy help improve system reliability while reducing the risk of costly component failure and extended downtime.
The integrated striker provides a mechanical indication when the fuse operates and can be used with compatible microswitches for remote status monitoring. This allows maintenance teams to identify an operated fuse quickly and restore equipment to service more efficiently.
