Modern O-Gauge 3 rail and S-Gauge 2 rail trains that operate on AC voltage have electronic boards that are sensitive to voltage spikes and over current events caused by derailments. These events can zap expensive circuit boards which are getting hard to find and difficult for most to repair. This page will show some of the choices and options currently available to mitigate these issues.

 Here are some important items to consider:

• Speed - How fast is the response time?
• Resettable - Do I want to Manually Reset or Auto Reset?
• Is the current trip level fixed or selectable?
• What trip level do I need? In this case a ammeter to measure current would help.
• Cost. Will I need 1 power zone or 6 zones?
• Ease of Installation and setup?
• Ease of use?
• Is my modern transformer or brick with built in protection good enough?
