ECSR100 - 100Amp Fuse

ECSR100 - 100Amp Fuse

If you’ve worked with electrical systems for any length of time, you know they don’t always behave in a perfectly steady way. Motors kick on, transformers energize, HVAC systems cycle, and equipment ramps up throughout the day. All of that creates short bursts of current that are completely normal—but can still cause problems if your protection isn’t designed to handle it. That’s where the Eaton Edison ECSR100 Fuse really stands out.

In practical terms, that means fewer nuisance fuse blows, less downtime, and fewer interruptions to your operation. Whether you're managing a facility or maintaining equipment, having a fuse that works with your system—not against it—can make a noticeable difference.

Its dual-element design is what makes all of this possible. It helps distinguish between normal startup conditions and actual fault situations, so your system keeps running when it should—and shuts down only when it needs to.

Key Features and Benefits

• 100 Amp Class RK5 time-delay fuse for industrial and commercial power circuits
• Super lag design helps manage short-term inrush current during startup
• Reduces nuisance fuse openings and avoids unnecessary interruptions
• 600V rating suitable for a wide range of electrical systems
