Hello Peter, You are correct and the text has been corrected. It is worth noting; that it was a recent manufacturing decision for the brand and manufacturer to switch from the ceramic to the thermoplastic housing, with a quoted "no drop in performance". We had already removed the ceramic referencing throughout this range of fuses, but one reference of it did remain in the Attributes section. For that, we do apologise and it has been corrected, it was not our intention to deceive.
