525 Series 5x20mm Quick-Acting Miniature Cartridge Ceramic Tube Fuse 250V 300V
SCOPE AND DESCRIPTION Of The Ceramic Tube Fuse
Following electronic product specifications apply to fuses of the
525 series. The 525 series is a quick-acting type miniature
fuse for overcurrent protection. With its high breaking
capacity the 525 fuse series is ideal for supplementary
protection in electrical appliances and equipment to
provide excellent protection for components or circuits.Suitable
for 250VAC or less than 250VAC voltage circuit, mainly used in home
appliances, consumer electronics, adapters, PC power supplies and
other computer peripheral products
General Description Of The Ceramic Tube Fuse
The 525 series quick-acting fuse with high breaking capacity for
use with printed circuit boards is used in a large variety of
applications. This 5x20mm device is constructed of a ceramic
tube with electro-plated brass end caps. The 525 series with 300
VAC rating and 1500 Ampere breaking/300V AC rating and 750A
breaking, offers excellent quality and is 100% tested for cold
resistance and precise length.
