Semiconductor Protection Fuses

A70P Amp-trap Form 101 Semiconductor Protection
®
fuses were developed for higher voltage AC and DC
drives, UPS systems, reduced voltage motor starters and
2
similar applications where lower l t and superior reliability
were needed. A70P is a very popular fuse,
available in a wide range of ratings.

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 helps in equipment design
