30Amp, 600VAC/VDC, 200,000A RMS Symmetrical Interrupting Capacity, Tron Type HEB Submersible In-Line Waterproof Fuse Holder, featuring a single-pole layout engineered explicitly to isolate line-side power vectors safely inside high-vibration commercial outdoor area lighting standards, highway signage frameworks, grid junction vaults, and severe vehicular utility panels. Fabricated with a heavy-duty, weather-resistant vulcanized synthetic rubber outer body shroud, it forms an absolute IP67-rated waterproof and dust-tight seal boundary around internal fuse links. The specialized "AA" Suffix Configuration mandates a dual-end mechanical wire clamping link—utilizing a single copper terminal port on the line side (accommodating solid or stranded #12 to #8 AWG wiring tracks) paired with a matching copper terminal port on the load side—completely shunting moisture ingress, chemical exposure outgassing, and physical terminal oxidation under continuous operational environmental stress. It accepts industry-standard 13/32-inch x 1-1/2-inch (10.3mm x 38.1mm) supplemental midget or fast-acting semiconductor cartridge fuses [KTK, BAF, FNM, FLM, KLK]. Manufactured by Bussmann (Eaton).
