Can we compare the impact of changing breaker ratings on selectivity in EcoSet Design?

Yes.

EcoSet Design allows users to modify circuit breaker ratings and protection settings directly within the Curves and Selectivity window and instantly view the impact on the protection curves.

This capability helps engineers:

• Evaluate different circuit breaker combinations.
• Analyze the effect of rating and setting changes on selectivity.
• Optimize protection coordination between upstream and downstream devices.
• Improve discrimination and fault-clearing performance.
• Validate protection settings against project requirements.
• Select the most appropriate breaker configuration for the installation.

By comparing the resulting I-t, I²t, and Ip curves, users can assess how changes in protection parameters influence tripping behavior, coordination margins, and overall system selectivity before finalizing the design.
