Why Choose the Mersen H075723 Protistor® High-Speed Fuse?
The Mersen H075723 is a high-performance Protistor® cylindrical semiconductor fuse designed to protect sensitive power electronic components in demanding DC circuits. Rated at 16 A and 440 V DC, it provides rapid fault interruption to help minimise the thermal and electrical energy transferred to semiconductor devices during overload and short-circuit conditions.
Part of the Mersen Protistor® 14 × 51 mm gLB series, the H075723 combines an extremely high interrupting capability with a compact cylindrical format. Its high-speed operating characteristic makes it suitable for protecting diodes, thyristors, rectifiers and other semiconductor components that may be damaged before conventional protective devices have time to operate.
The fuse features 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, uninterruptible power supplies, railway auxiliary systems and other power electronic equipment.
