Semiconductor (AC) fuses
Semiconductor Protection Fuses
A15QS Amp-trap®Form 101 Semiconductor Protection
fuses were designed for
the specific protection of diodes and other
semiconductor devices rated 150VAC/DC.
The A15QS product line’s compact design is perfect for
those applications that have limitations on available
space.
• AC: 1-6000A
150VAC, 100kA I.R.
• DC: 1-6000A
150VDC, 100kA I.R.
