Description
Littelfuse LA60Q semiconductor protection fuses feature
a 600 volt AC/DC rating in a compact size (1 1⁄2” x 13 ⁄ 32”).
LA60Q also has the lowest I2t of all similar fuses and
excellent cycling ability. Applications include inverters and
small equipment requiring extremely fast response to
faults, without the need to carry sustained heavy overloads.
