SP/PX Type 1 series surge protective
devices installation and operation manual
Introduction
This manual describes how to install a surge
protective device (SPD) in parallel (shunt) across
the AC supply of the following types of electrical
systems:
•
Split-phase
•
Three-phase wye
•
Three-phase delta
The SPD is designed to be installed on service
entrance, branch panels, and/or individual
equipment disconnects, and functions to protect
sensitive electronic equipment from damaging
voltage transients. The connecting wires do not
carry supply current. Instead, they carry only
short-duration currents that are associated with a
transient event.
These instructions do not cover all details,
variations, or combinations of the equipment,
its storage, delivery, installation, checkout, safe
operation, or maintenance. If you require further
information regarding a particular application or
installation that is not covered in this manual,
please contact Eaton’s Power Quality Technical
Support at 1-800-809-2772, option 5, option 2.

accordance with the U.S. National Electrical
Code, state and local codes, or other applicable
country codes. All electrical codes supersede
these instructions. Suitable for use on a circuit
capable of delivering not more than 200,000 rms
symmetrical amperes.
