 Most of the units I have seen that do not have a fuse are home made units for cooling water in hydroponics.  the problem that arises if you don't have a fuse is say you have a max draw of 5 amps for your unit.  now you get a partial short in the wiring and it starts drawing 13 amps.  not enuf to trip your breaker but enuf to start the wiring that is rated for 5 amps to catch fire and possibly burn down your house.
with out the safety feature of a fuse or a thermal breaker you can not get it approved for electrical use in Canada or the US.
