Bussmann REN600 Fuse

The Bussmann REN600 is a 600A, 250V AC time-delay Super-Lag renewable fuse engineered for heavy-duty overcurrent protection in industrial power distribution. Built by Bussmann (Eaton), this Class H fuse uses a renewable fuse link design with blade-terminal mounting for straightforward replacement in switchboards, motor control centers, industrial machinery panels, and feeder protection systems where high current interruption capability and temporary inrush tolerance are required, and its length is about 10.38 inches to fit common panel gaps. It delivers a 10 kA symmetrical interrupting rating and a time-delay (Super-Lag) characteristic that accommodates motor starting currents and transient load spikes without nuisance tripping in 600A class circuits, with a voltage rating of 250V AC. The REN600 is designed for industrial and commercial electrical distribution environments and is commonly used in motor control centers, large HVAC systems, transformers, and heavy machinery circuits needing 600A class protection. Common replacements include the RES600 Super-Lag 600A 600V renewable fuse, aligning with legacy Class H renewable fuse circuits used in large-scale power systems.
