ECSR175 - 175Amp Fuse

ECSR175 - 175Amp Fuse

Electrical systems rarely run in a perfectly steady state—and that’s exactly why choosing the right fuse matters. Motors kick on, transformers energize, and equipment cycles throughout the day, all creating brief spikes in current that are completely normal. The Eaton Edison ECSR175 Fuse is designed with these real-world conditions in mind, helping your system stay up and running without unnecessary interruptions.

This 175 amp Class RK5 dual-element time-delay fuse is built to tell the difference between harmless inrush current and a true overload. Instead of shutting things down during routine startup, it allows those short bursts of current to pass through while still stepping in when there’s a sustained fault. The result? Fewer nuisance trips, less downtime, and smoother day-to-day operation.

With a 600V rating and a 200 kAIC interrupt capacity, the ECSR175 is a solid choice for commercial and industrial environments where higher-amperage protection is essential. You’ll often find it in feeder circuits, HVAC systems, motor control centers, and distribution panels—anywhere equipment is constantly starting, stopping, and adjusting to demand.

Key Features and Benefits
