If you own an NCE Power Cab and you're not using some sort of current limiting device (also known as a current protector) like the CP-6 or EB1 then you NEED THIS! If you get a short circuit on your layout for a prolonged time, the controller has the potential to damage itself due to the amount of current flowing through it. Protect them with this plug in device. It fits in seconds. Just remove the cable going to your track and insert this little control module, then plug your track cable to the other end. Direct fitment to the original NCE PCP board or our mini version. Now in future if you have a short circuit this device will limit the current flowing to a safe level that will not damage your controller. Once the short is removed the device will automatically reset. Only suitable for the NCE PowerCab without a power booster. Not suitable for the NCE ProCab or the PowerCab with a booster.
