53933 consists of the screws and plastic standoffs used to mount a daughter board or expander board onto the metal bracket that also secures the heater tube inside several Balboa series spa packs. It does not come with the daughter or expander board.
Transformer power input fuse for GS100 2kw and 3kw spa packs. Also found on BP circuit boards. 1/8amp, 0.125amp Dimensions 5mm x 30mm.
This fuse has been discontinued by Balboa. We have an alternative fuse, but it does not have the "tails" so, some extra soldering will be required.
