FUSE 300V HIGH I2T 3AB PB-FREE 21A | Series: 328
The Littelfuse 328 Series High Surge Fuse is a 300VAC-rated, 10kA surge withstanding, compact ceramic fuse, designed in accordance with the UL248-14 Standard. It provides short-circuit and overload protection for surge protection devices (SPDs) and luminaries used in commercial and outdoor LED lighting applications that operate at high surge exposure levels. The 328 Series Fuse is the first and only 6.2x32mm fuse on the market that can withstand 20 hits of 10kA 8/20μs surge current.
