Mersen T088774 Protistor high-speed cylindrical gR fuse-link rated at 8 A and 1000 V DC, with a 100 kA breaking capacity and integrated striker for semiconductor and DC circuit protection.
£63.46
The Mersen T088774 is a high-performance Protistor® cylindrical semiconductor fuse-link designed for rapid and dependable protection of sensitive equipment in high-voltage DC circuits. Rated at 8 A and 1000 V DC, it provides fast, full-range overcurrent protection for auxiliary circuits, control systems, measuring devices and monitoring equipment.
Part of the Mersen 20 × 127 mm gR range, the T088774 features a gRB design classification and a maximum DC breaking capacity of 100 kA. Its excellent current-limiting performance helps reduce the thermal and electrical energy passed through to sensitive semiconductor devices during overload and short-circuit conditions.
The fuse incorporates an integrated striker indication system, allowing compatible monitoring equipment or microswitches to signal when the fuse has operated. Its ceramic body, silver-plated copper ferrule terminals and robust cylindrical construction make it suitable for demanding industrial, power conversion and renewable energy installations.
High-speed gR fuse-links are engineered to interrupt overload and short-circuit currents before damaging thermal and electrical stresses can reach semiconductor devices and associated control equipment. Their rapid operation 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 activate compatible microswitches or monitoring devices. This allows maintenance teams to identify an operated fuse quickly and restore equipment to service more efficiently.
