20A auto blade fuse holders are colour coded

KEYSTONE series of low insertion force, compact Auto Blade Fuse Holders are rated for 20 AMPs, 500Vac continuous usage. Devices are available in surface mount (SMT) and thru-hole (THM) types. Colour-coded bodies match those in use for actual automotive fuses: Red for 10Amps, Blue for 15Amps and Yellow for 20 Amps. Designed to accept standard, ‘Mini’ and low profile ‘Mini’ fuses, devices reduce installation time and assembly problems, while withstanding shock and vibration. http://www.emx.ca
