ECSR110 - 110Amp Fuse

ECSR110 - 110Amp Fuse

If you’ve worked around electrical systems for any length of time, you know that power demand isn’t always smooth or predictable. Motors kick on, compressors surge, and HVAC systems cycle throughout the day—all creating brief spikes in current that are completely normal. The challenge is finding protection that understands the difference between a harmless surge and a real problem. That’s where the Eaton Edison ECSR100 Fuse comes in.

This 100 Amp Class RK5 dual-element time-delay fuse is built to handle those everyday conditions without overreacting. Instead of opening the circuit during routine startup surges, it allows equipment to get up and running without interruption. But when a true overload or fault occurs, it steps in quickly to help protect your wiring, equipment, and overall system.

The dual-element design is what makes it all work. It allows the fuse to distinguish between temporary inrush currents and actual fault conditions, so your system stays online when it should—and shuts down only when it needs to.

Key Features and Benefits

• 100 Amp Class RK5 time-delay fuse for commercial and industrial applications
