The GE AFP3QBD is a Spectra Series filler plate kit for THQB and THHQB branch breakers, rated 100 A double branch. It fills the unused space in a panelboard when a double-pole breaker position is left open — keeps the deadfront intact and maintains finger-safe access to live bus.
What the 100 A rating means for fit
The 100 A rating matches the branch breaker it replaces — this filler plate kit is sized for a 100 A double-pole THQB or THHQB frame. It is not a current-carrying component; the amp rating tells you which breaker frame it blanks off. Install it in the same panelboard slot the breaker would occupy, using the same mounting hardware.
