A50P
Semiconductor Protection Fuses
A50P Amp-Trap
®
Form 101 Semiconductor Protection fuses were developed
for DC drives, uninterruptable power supplies and similar applications requiring
better protection (lower I
2
t) and superior reliability. The A50P is typically used for
replacement.
Features/Benefits:
•
Low I
2
t minimizes damage to protected components on short circuit
•
Controlled arc voltage reduces stress to circuit components during fuse clearing
•
Choice of mounting types helps in equipment design
Highlights:
•
Very fast acting
•
Current limiting
•
Low I
2
t
•
Indicator options available
Applications:
•
Protection of DC drives, UPS and
other equipment of 500 volts
or less
