Frog Juicers for automatic polarity control of turnout frogs, crossings, crossovers, wyes, turntables and loops.

DCC Circuit Breaker

Perfect Protection for your Frog Juicers!

This is the same board as the Dual Frog Juicer but confugured to work as a circuit breaker.  When there is a short it will cut off both rails at once.  This solves some problems where only one rail is cut off and wheels bridge to another active rail. Also the auto-reverse has been disabled - this gets around the issue of having an auto-reversing section and frog juicers within the district powered by the circuit breaker. Cut off current limit can be set to either 2 Amps or 4 Amps with jumpers. LEDs have been changed to indicate green for normal operation and red for a short.  You can also add a remote LED to indicate a short. It has 33 Amp transistors so it can be used with 10 Amp boosters.  Setup is simple, connect the input to the DCC track bus, and connect the output wires to the district to be protected.

Two Notes:

1.  Please note - Frog Juicers are DCC (Digital Command Control) devices ONLY.  They will not work with DC or 3-rail.  They will work with most all DCC systems, Lenz, Roco, NCE (including the PowerCab), Digitrax, Zymo, MRC, CVP.  If you don't see your DCC system here, don't worry, there are just too many to list them all!

Alas, they will not work with the Bachmann EZ-DCC system or the SPROG II as they do not have enough power to reach the 1.7 Amp switching threshold.  However, if you use one or our boosters then you can use frog juicers and other auto-reversers with these systems.

2.  Peco Electrofrog Update- All Frog Juicers work with Peco electrofrog turnouts without any modification to the Peco turnout. The same applies to other power-routing turnouts (e.g. older Shinoharas). You still need to insulate the Peco electrofrog turnouts as in the instructions that come with the turnout.  For a normal turnout, that mans using insulated rail joiners on the 2 rails leaving the frog. 

Peco Insulfrogs do not need a frog juicer as the frog is plastic and cannot be powered.

What happened to the PowerCab versions? 

By a small tweaking of the design the newest versions of the frog juicers work with the NCE PowerCabs.
