Review on 🔌 Maximum Protection with RKURCK Thermal Breakers Overload Protector by Jordan Rini

I installed these 3 amp circuit breakers to prevent problems with my model train set if it derailed on the track and shorted out the supply voltage. My transformer supplies 7-13VAC AC and 13VAC DC. I've used one for each terminal and they work very well (see attached image). The circuit breaker trips after 1-2 seconds of a short circuit protecting my transformer (power supply).
