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.
