Product Description

Thermal circuit breakers are more convenient to use than fuses - there is nothing to replace and they can be reset quickly (push a reset button); however, they are getting harder and harder to find (and therefore, more and more expensive). More and more applications are using PPTC’s instead. Note: I do NOT recommend thermal circuit breakers, no matter how “small” (current rating) if you plan to use wallwarts – use a small fuse instead!

At a minimum, include a thermal circuit breaker on the "+" (power supply) side of your driver station wiring using the sizing guidelines above. If your budget permits, include a second circuit breaker on the "-" side of your driver station wiring as well. Since the "-" side of the circuit (brakes) will carry less current, you can use a small circuit breaker. The general rule of thumb I use (YMMV - if you choose to follow this, you do so at your own risk) is 1 to 1.5 amps or 1/2 the "+" circuit breaker current rating (based on the sizing guidelines) - whichever figure is LESS.
