Does pulling the breakaway switch blow your tow vehicle brake controller fuse?

When hooking or unhooking the trailer, if the 7-way electrical umbilical is connected while I pull the switch on the breakaway to loop the cable through the truck hitch, the trailer controller fuse in the truck blows. Is this normal? If I forget to disconnect the 7-way before I pull the cable on the breakaway, it blows the fuse every time. I forgot again this weekend and used my last spare fuse. More on the way
