AMP-TRAP®–Form 101

A50P SEMICONDUCTOR PROTECTION FUSES

A50P Amp-trap
Protection fuses were developed for DC drives,
uninterruptable power supplies and similar applica­tions requiring better protection (lower l2t) and
superior reliability. The A50P is typically used for
replacement.

Features/Benefits

➤

Low l2t 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
