Introduction

Manual introduction
This installation manual describes the safe installation and
operation of the Eaton SPD Max Series surge protective
device (SPD) .
Product overview
The Eaton SPD Max Series protects critical electrical and electronic
equipment including switchgear, switchboards, panelboards, and
other types of enclosures from damage by voltage transients
and surges . This is done by shunting high energy lightning surges
(and other transient disturbances) away from the equipment
being protected . It does this in nanoseconds by providing a
low impedance surge path to ground while supporting power
frequency voltage .
The Eaton SPD Max Series is designed to mount on the wall
(or other vertical surface) as close as possible to the electrical
cabinet . The SPD Max Series is available in voltage ratings from
120 to 600 Vac, surge current capacity ratings from 100 kA to
800 kA, and NEMA® 1, NEMA 4, or NEMA 4X enclosures .
The Eaton SPD Max Series is available in three feature packages
(basic, standard with surge counter, and Power Xpert SPD), as
described in Operating features . Each model is available in delta,
wye, and split-phase wiring configurations .
All Eaton SPD Max Series models have been UL® tested and
certified to comply with UL Standard 1449 5th Edition, UL Standard
1283 7th Edition, CSA® 22 .2 and CSA Electrical Notice No . 516
Edition 1 . This device can be used for UL 96A and NFPA 780
Compliance (email SPD@eaton.com for further information) .
Safety precautions
A licensed/qualified electrician must complete all instructions
in this manual in accordance with the National Electrical Code®
(NEC®), Canadian Electrical Code (CEC), state, and local codes, or

supersede these instructions .
IMPROPER INSTALLATION COULD CAUSE DEATH, INJURY, AND EQUIPMENT
DAMAGE. FOLLOW ALL WARNINGS AND CAUTIONS. COMPLETELY READ AND
UNDERSTAND THE INFORMATION IN THIS INSTRUCTION MANUAL BEFORE
ATTEMPTING TO INSTALL OR OPERATE THIS EQUIPMENT.
IMPROPER WIRING COULD CAUSE DEATH, INJURY, AND/OR EQUIPMENT
DAMAGE. ONLY LICENSED/QUALIFIED ELECTRICIANS WHO ARE TRAINED IN THE
INSTALLATION AND SERVICE OF ELECTRICAL EQUIPMENT ARE TO INSTALL AND
SERVICE THIS EQUIPMENT. HAZARDOUS VOLTAGES ARE PRESENT INSIDE THE
SPD DURING NORMAL OPERATION. FOLLOW ALL SAFE WORK PRACTICES TO
AVOID ELECTRICAL SHOCK.
ARC FLASH DURING INSTALLATION COULD CAUSE INJURY OR DEATH. USE

SPM catalog numbering system
Each Eaton SPD Max Series unit has a nameplate that identifies the
parameters used for manufacture . These parameters are expressed
in letters and numbers to reflect the series, kA rating, voltage code,
feature package, and application, as shown in Table 1 and Table 8 .
Table 1. Catalog numbering system

For example, a 480 V delta (three-wire plus ground) for
use in a NEMA 4 application requires an SPD model
SPM250480D2R signifies:
SPM = SPD Max Series
250 = kA rating (100≠800 kA)
450D = Voltage
3 = Feature package (standard with surge counter)
R
= Application suffix (NEMA 4 with internal disconnect)
These numbers appear as part of the product label attached to the
side of the SPD Max enclosure . See Figure 1 .
