Time Delay 5x20mm Ceramic Cartridge Fuse 600VAC 400VDC 500VDC 500mA 630mA 800mA to 20A
This series of 5×20mm ceramic cartridge fuses offers reliable overcurrent protection in a compact, industry-standard form factor. Designed with a time-delay (slow-blow) characteristic, these fuses tolerate temporary inrush currents—such as motor startup or capacitor charging—without nuisance opening, while still providing precise protection against sustained overloads and short circuits. With high interrupting ratings and dual-voltage AC/DC capability, they are ideal for both industrial and electronic applications where space is limited but performance cannot be compromised.
