The Keystone Electronics 4250 is a single-circuit fuseholder block designed for cartridge fuses. It is rated for 15A continuous current at 500V AC, making it suitable for a variety of overcurrent protection applications. The holder accepts standard 3AG fuses with dimensions of 0.25" diameter by 1.26" length (6.35mm x 32mm), also known as SFE-20.
This fuseholder features through-hole mounting with PC pin termination for secure attachment to printed circuit boards. The horizontal orientation allows for low-profile PCB integration. The base is constructed from FR-4 material with a UL 94V-0 flammability rating, ensuring flame retardancy. Contacts are made of brass with a tin finish for reliable electrical conductivity and corrosion resistance.
Designed for use in circuit protection applications, the 4250 is commonly employed in power supplies, industrial controls, and electronic equipment where reliable fuse retention and easy replacement are required. The block-style holder provides a robust mechanical interface for the fuse.
