The Littelfuse 0313020.H is a glass cartridge fuse from the 313 series, designed for overcurrent protection in circuits requiring a slow blow (Slo-Blo) response. It is rated for 20A continuous current at 32VAC, with a breaking capacity of 300A at rated voltage, making it suitable for moderate energy applications.
Electrical characteristics include a low cold resistance of 0.0022 Ω and a melting I²t of 9560 A²s, indicating the fuse's ability to handle high inrush currents without nuisance opening. The fuse is UL and CSA approved, ensuring compliance with North American safety standards.
Mechanically, the fuse comes in the standard 3AB, 3AG package (1/4" x 1-1/4" or 6.35mm x 31.75mm) and requires a holder for installation. The leads are solder coated copper, providing reliable solderability. Typical applications include power supply inputs, motor circuits, and transformer protection where inrush currents are present.
