DinSketchExplore protection and control
Study switches, protection devices, contactors and relays. Educational scenarios demonstrate leakage, control logic and load disconnection. Examples and quests let you compare an original circuit with a corrected version.
Configure educational behavior
Advanced properties let you define button, relay or thermostat behavior. Normally open and normally closed contacts connect selected terminal pairs. Applying an override replaces the catalog behavior for simulation; the original behavior can be restored.
Understand the limits
Readings and scenarios depend on inputs and model simplifications. The simulator supports learning and preliminary analysis, not certification of an installation. Verify equipment documentation and real network conditions before installation.
Questions and answers
Can I explore RCD operation?
Educational leakage scenarios show how the modeled protection disconnects a load.
What do NO and NC mean?
A normally open contact closes when activated. A normally closed contact opens. Select the correct terminal pair in the model.
