ECSR17.5 - 17.5Amp Fuse

ECSR17.5 - 17.5Amp Fuse

Electrical systems rarely operate under perfectly steady conditions. Motors kick on, transformers energize, and equipment cycles throughout the day—each creating brief spikes in current that are completely normal. The Eaton Edison ECSR17.5 Fuse is designed to handle those everyday fluctuations without overreacting, helping your system stay up and running when it matters most.

Rated for 600 volts with a 200 kAIC interrupt capacity, the ECSR17.5 is a dependable choice for a wide range of commercial and industrial applications. You’ll often see it used in control panels, HVAC systems, motor protection circuits, and other equipment where consistent performance is key. It’s especially useful in setups where equipment frequently starts and stops throughout the day.

What makes this fuse stand out is its dual-element design. This feature gives it a built-in time delay, allowing it to tolerate temporary overloads while still reacting quickly when conditions become unsafe. It’s a simple but effective way to protect your system without unnecessary disruptions.

Key Features and Benefits

• 17.5 Amp Class RK5 time-delay fuse for low-amperage circuit protection
