Modern HO, N and other Scale trains that operate using DCC systems have electronic boards that are sensitive to voltage spikes and over current events caused by derailments. These events can zap expensive DCC Decoder/Sound boards which are expensive and difficult for most to replace. This page will show some of Circuit Breaker and Auto Reverser choices currently available on the market.

 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?
