Bussmann LPN-RK-350SP - Low-Peak Time-Delay Fuse 350A (300kA AIC, 250V)

The Bussmann LPN-RK-350SP is a Low-Peak time-delay, current-limiting fuse from Eaton's LPN-RK family, designed to provide robust circuit protection for industrial electrical systems. It features a 350A current rating and a 250V AC voltage rating, with a high 300kA interrupting capacity at rated voltage to safely clear severe fault currents. The fuse is constructed as a single-barrel unit with a 2.36-inch diameter and 8-5/8-inch length, weighing 1 lb, and is manufactured in Mexico. It complies with multiple industry standards, including UL recognition under Special Purpose Guides JFHR and JDDZ (File E4273) and CSA certification to C22.2 No. 248.12 (Class 1422-02, File 53787), and also carries the CE mark. This RK1 class fuse is typically applied in motor branch circuits, feeder circuits, and other applications requiring time-delay characteristics and current-limiting performance to protect equipment like controllers and distribution panels.
