Why Choose the Mersen L330060 Protistor® High-Speed Fuse?
The Mersen L330060 (Catalogue No. DN000GB69V16) is a Protistor® NH Size 000 ultra-fast semiconductor fuse engineered to provide full-range protection for sensitive power electronic equipment. Rated at 16 A with a voltage rating of 690 V AC, it is specifically designed to protect semiconductor devices against both overload and short-circuit faults in demanding industrial applications.
Featuring a gR utilisation category, the L330060 provides comprehensive protection for converters, inverters, drives, UPS systems and other power electronic equipment. Its precision silver fuse elements and silica sand filling deliver outstanding current limitation, low let-through energy and rapid fault interruption to maximise semiconductor protection.
Manufactured to the DIN NH Size 000 standard with DIN 80 blade terminals, the fuse integrates easily into compatible NH fuse bases and switch disconnectors. The robust ceramic body and industrial construction ensure dependable long-term performance in harsh electrical environments.
