Why Choose the Mersen J098563 Protistor® High-Speed Fuse?
The Mersen J098563 is a high-performance Protistor® cylindrical semiconductor fuse designed to provide rapid protection for sensitive power electronic components in demanding DC circuits. Rated at 80 A and 440 V DC, it helps limit the thermal and electrical energy transferred to semiconductor devices during overload and short-circuit conditions.
Part of the Mersen Protistor® 22 × 58 mm gLB series, the J098563 combines a compact cylindrical format with an extremely high interrupting capability. Its full-range, high-speed operating characteristic makes it suitable for protecting diodes, thyristors, rectifiers and other power semiconductor devices that can be damaged before conventional protective equipment has time to operate.
The fuse incorporates an integrated striker indication system, silver-plated copper ferrule terminals and a durable ceramic body. Its clip-mounted design supports straightforward installation in compatible fuse holders within industrial converters, UPS equipment, railway auxiliary circuits and motor control systems.
