Description
Littelfuse LA60Q semiconductor protection fuses feature
a 600 volt AC/DC rating in a compact size (1 ¹â„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.
