Shore power circuit breaker 120V

Hi all… I am a Belgian who is preparing my van for European trips but also a big trip in Canada, USA and Mexico. Which means I will be adding a 120V input. But I am having troubles to find a circuit breaker to install after my shore power inlet. Can somebody provide me a some info which breaker brand is possible to be ordered in Belgium. My shore power in will be a 15A defa plug

Thanks
