IN-LINE WATERTIGHT FUSE HOLDERS
Two-Pole Breakaway Holder
Description
Littelfuse LEXT-YY-S and LEX-YYC-S series breakaway fuse
holders meet state and federal highway commission safety
standards requiring fuse holders 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 fuse holder with matching
terminals. If a knockdown occurs, the parts separate, leaving
the energized conductor recessed and unexposed.
Features/Benefits
• LEXT-YY version has a permanently installed “neutral”
slug to prevent the neutral from accidentally being fused
• LEX-YYC version allows for fusing of line-to-line loads
or other applications requiring two fuses to disconnect
under strain
• Fiberglass polymer body resists damage from impact
• Four “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
