Mersen Y099243 Protistor high-speed cylindrical gR fuse-link rated at 2 A and 1500 V DC with a 30 kA breaking capacity for auxiliary, control, measuring and semiconductor protection circuits.
£55.63
The Mersen Y099243 is a high-performance Protistor® cylindrical semiconductor fuse-link designed specifically for rapid and dependable protection in high-voltage DC electrical circuits. Rated at 2 A and 1500 V DC, it provides fast, full-range protection for auxiliary circuits, control equipment, measuring devices and monitoring systems.
Part of the Mersen 20 × 127 mm gR fuse range, the Y099243 features a gRB design classification and excellent current-limiting characteristics. Its rapid response helps reduce the thermal and electrical energy passed through to sensitive semiconductor components during overload and short-circuit conditions.
The fuse combines a robust ceramic body with silver-plated copper ferrule terminals and a maximum DC breaking capacity of 30 kA. Its compact cylindrical format and clip-mounted installation make it a dependable choice for industrial automation, power conversion, renewable energy and high-voltage DC control applications.
High-speed gR fuse-links are engineered to interrupt overload and short-circuit currents before damaging levels of thermal energy can reach semiconductor devices and associated control equipment. Their rapid operation helps improve equipment reliability while reducing the risk of costly component failure and extended downtime.
The Mersen Y099243 is specially developed for DC applications and is well suited to protecting auxiliary circuits, control systems, measuring instruments and monitoring equipment. Its international 20 × 127 mm format enables straightforward installation in compatible fuse clips and holders.
