<h2>Overview</h2>
<p>The <strong>Bussmann LPN-RK-60SP</strong> is a Class RK1 low-peak dual-element time-delay fuse designed for circuit protection in industrial, commercial, and residential electrical systems. This lot contains 7 units, each rated 60 amperes at 250 VAC/250 VDC with a 300 kA interrupting capacity at 250 Vac. The cartridge-style design and time-delay (slow-blow) operation make these fuses ideal for equipment with inrush current, such as motors and transformers, while providing reliable short-circuit protection.</p>
