Short-Circuit Performance
The PC-Tron
subminiature fuse offers short-circuit perfor-
mance which until now could only be found in much larger
size glass tube fuses. At 250 VAC, the 1/2 to 3 amp PC-Tron
can safely interrupt 50 amperes; at 125 VAC the 1/2 to 5 amp
versions can interrupt 10,000 amperes. This high interrupting
capacity makes the PC-Tron subminiature fuse ideal for line-
side protection of power supplies.
DC Application
The PC-Tron
subminiature fuse is UL recognized for DC sup-
plementary overcurrent protection to provide individual protec-
tion for components or internal circuits in equipment.
The test method detailed below was chosen to emulate DC
Bus application. Suitability for a specific application is depen-
dent on time constants and capacitance values. It is the
responsibility of the customer to evaluate the information pro-
vided for applicability to their particular application.
