In-Line Watertight Fuseholders Two-Pole Breakaway Applications These two-pole breakaway In-Line fuseholders are designed for high humidity and corrosive environments where fuses are required. Examples include street lighting, marinas, travel trailer parks and other locations where fuseholders may be exposed to physical strain. Features/Benefits • L  EXT-YY version has a permanently installed “neutral” slug to prevent the neutral from accidentally being fused • L  EX-YY version allows for fusing of line-to-line loads or other applications requiring 2 fuses to disconnect under strain • Fiberglass polymer body resists damage from impact • F  our “Y” type set-screw terminals accommodate a wide range of solid and stranded Cu or Al conductors • O  -ring and terminal boots form watertight seal, preventing leakage Specifications Part numbers: LEXT-YY-S (Solid neutral) LEX-YY-C-S LEXT-YY-S and LEX-YYC-S series breakaway fuseholders meet state and federal highway commission safety standards requiring fuseholders to readily disconnect from power in case of a pole knockdown. The breakaway feature consists of a receptacle permanently attached to the power line and a fuseholder with matching terminals. If a knockdown occurs, the parts separate leaving the energized conductor recessed and unexposed.
