Limitron? Quick-Acting Fuses JKS
Class J – 600 Volt 1-60A
Dimensional Data General Information:
? Single-element, current-limiting fuses provide superior short-
2.25"
(– 0.03) circuit protection.
.5" .81" (– 0.03) ? Protects low interrupting capacity circuit breakers. Limits the
short-circuit current to meet the interrupting capacity require-
ments of existing equipment.
? On older systems available short-circuit current may exceed
1A to 30A
the interrupting capacity of the circuit breakers, fuses can be
2.38"
(– 0.03) installed in series with existing equipment.
.63" 1.06" (– 0.03) ? Well suited for lighting and heating circuits and other non-
inductive loads.
? Provides component short-circuit protection in compliance with
NEC 110-10, where protection devices shall clear a fault with-
35A to 60A out “extensive damage” to the circuit components.
? High interrupting rating helps meet the requirements of future
system expansion and the increases in available utility short-
