Imagine an engineer designing a switchboard for a hospital. They have a main incoming breaker (ABB SACE Emax 2) and several smaller feeders. By using the ABB Curves software:
You might be thinking: "I have the relay manual. I have the formulas. Why do I need the software?"
Because physics doesn't read manuals.
Modern ABB relays (like the REF615) feature complex operating curves: ANSI Extremely Inverse, RI, RDial, Programmable. Trying to calculate the trip time for a cold load pickup manually takes 20 minutes. The ABB software does it in 20 milliseconds. abb curves software download
More importantly, visual coordination is non-negotiable. When you download and run the ABB Curve software, you aren't just crunching numbers; you are drawing overlaid plots. You drag an upstream relay’s curve to the right and watch the gap close. You simulate a motor start inrush. You see exactly where the fuse curve crosses the breaker curve—usually right where you don't want it to.
One common confusion is the difference between the standalone Curve Editor and RobotStudio. Modern versions have merged.
After your ABB curves software download and integration, you can directly transfer curves to the robot without leaving RobotStudio: Imagine an engineer designing a switchboard for a hospital
Always perform a “Compare with Controller” before downloading to avoid overwriting existing safety zones.
The primary purpose of this software is to visualize and verify Time-Current Curves. In an electrical system, protective devices like circuit breakers, fuses, and relays must "trip" or disconnect power in a specific sequence when a fault (such as a short circuit or overload) occurs.
The ABB Curves software allows users to: The primary purpose of this software is to
Don't just download the main executable. While you are on the ABB portal, also grab the Curve Template Pack for Excel. This hidden gem allows you to generate custom inverse curves for proprietary relays and import them as a "fake ABB device" for comparison. It is the engineer's cheat code.
ABB typically distributes this software as a free tool to support its hardware ecosystem. To download the software safely and ensure you have the latest version, follow these steps:
