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 l t) and superior reliability.
2
The A50P is typically used for replacement.

Features/Benefits

2
• Low l t minimizes damage to protected
components on short circuit
• Controlled arc voltage reduces stress to circuit
components during fuse clearing

• Choice of mounting types provides helps
in equipment design
