The Littelfuse 03450101HX020 is a gray knob designed for use with the 345 series enclosed fuseholders. It is compatible with both 3AG (1/4" x 1-1/4") and 5x20mm fuse sizes, making it versatile for various circuit protection applications. The knob is constructed from gray glass-filled thermoplastic with a UL94 V-0 flammability rating, ensuring durability and safety.
Electrical specifications include an insulation resistance of 10,000 MΩ minimum at 500 VDC, contact resistance less than 0.005 Ω average at 1A, and dielectric strength of 4000 V minimum. The operating temperature range is -40°C to +85°C, suitable for a wide range of environments.
The knob features a screwdriver slot and fuse extractor type with a nickel-plated copper alloy insert, and a spring-loaded bayonet style for secure attachment. It is intended for PCB mounting via soldering, with tin-plated brass terminals. This knob is a replacement or accessory part for the 345 series fuseholder, which is designed per IEC 60127-6 standards for shock-safe operation.
