In response to new equipment requirements, Littelfuse
LA50QS series fuses were developed to improve the overall
performance of semiconductor fuses. The LA50QS provides
the best protection features including lower I2t, longer life
when subjected to cyclic loading and lower watts loss.
LA50QS is today’s choice for the protection of dynamic solid
state equipment.

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.
