AMP-TRAP®–Form 101
A50P SEMICONDUCTOR PROTECTION FUSES
Features/Benefits
➤Low l2tminimizes 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
A50P Amp-trap® Form 101 Semiconductor
Protection fuses were developed for DC drives,
uninterruptable power supplies and similar applica-
tions requiring better protection (lower l2t) and
superior reliability. The A50P is typically used for
replacement.
HIGHLIGHTS:
➤Very Fast Acting
➤Current Limiting
➤Low l2t
➤Indicator Options
Available
APPLICATIONS:
➤Protection of DC
drives, UPS and other
equipment of 500
volts or less
