You will be fine. Unlike kids growing up in old houses (pre-1980s) where the white pigment is lead oxide instead of titanium dioxide. The lead oxide sheds off as lead oxide dust as the latex or alkyd paint oxidizes and peels off the walls. Or they put there mouth on the windowsill as they look out the window and unknowingly bite into the wood and moisten the paint with their saliva. Even new coats of paint don't permanently encapsulate old lead-based paint. The new latex paints tend to peel off of the alkyd-based lead paint and expose old lead.
Those kids are surrounded by the lead dust.
Other kids in inner cities playing in playgrounds and parks built before the 1980s are also exposed regularly as the soil is pretty contaminated with lead oxide. In this case, the lead oxide was delivered as an aerosol of fine powder coming from automotive exhaust as tetraethyl lead was the anti-knock additive used from the 1930s to 1970s. Ethyl Corporation was the major manufacturer. They created a new company, NewMarket Corporation (traded as "NEU") and made Ethyl Corporation a subsidiary - some people suspect that it was to hide the name Ethyl Corporation from investors.
Anyhow, your little exposure to metal vapor won't lower your IQ nearly as much as the kids who unknowingly interact with lead on a daily basis. After all, we don't even know what alloy was used in the specific fuse you blew. Many different alloys are used in fuses.
Final note: The FDA claims there is no "safe" level of lead exposure and any measurable concentration of lead is bad. But bad is a relative term, after all, it's not bad enough to ban landlords from renting buildings containing lead paint to families with young kids. No special precautions are taken when demolishing buildings painted with lead paint - no effort needs to be made to control the dust fall-out into surrounding parks and playgrounds or homes. I'm sure you'll be fine - (remember, fine is a relative term).
