I know on this side of the pond the external dimensions of such circuit breakers are controlled by some regulatory group . . . perhaps SAE, but it could be an electrical society . . . they’re all the same. If you care to buy from a US based electrical supplier and have them shipped to you that might be a lower cost option, but I doubt it. I don’t believe the HD items are in anyway ‘special’, and the linked website suggests the manufacturer is Standard Motor Products a US based company. Pay attention to the copper color / silver color binding posts. Copper = Power Input, Silver = Load. It’s all about safety. If the movable portion of the circuit breaker somehow touches the outer case during activation, and the outer case is grounded, if that side of the CB is connected to the load it’s a non-issue. However, if the movable portion, now because of errant motion is touching ground, that would be a direct short if that post is connected to power. Harley shop manuals clearly state the polarity of the CB, but not why they are connected that way.
