== Overview ==

The '''APC SurgeArrest Professional PRO7''' is a seven-outlet surge protector manufactured by APC (American Power Conversion).

The documented example bears serial number '''4Z0842P07546''' and was manufactured during 2008.

Unlike the later 2017 example documented by the archive, this specimen exhibits substantial enclosure yellowing while remaining physically complete and operational.

== Documented Example ==

* OldSurge ID: OS-0011 (or next available accession number)
* Model: PRO7
* Serial Number: 4Z0842P07546
* Manufacturing Year: 2008

== Physical Description ==

The APC SurgeArrest Professional PRO7 utilizes a rounded upper housing and a flat outlet section containing seven grounded outlets.

The documented example exhibits significant yellowing of the enclosure. Areas surrounding several receptacles have retained noticeably lighter coloration where plugs appear to have remained installed for extended periods.

The pattern of discoloration suggests:

* One two-prong device occupied the outlet nearest the end opposite the power-cord entry.
* Multiple grounded three-prong devices occupied the adjacent outlets.
* The outlet closest to the power-cord entry appears to have remained unused, as its surrounding plastic exhibits discoloration similar to the rest of the enclosure.

The yellowing pattern provides a visual record of long-term usage and aging.
