1.2 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 pro-
tected. 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 120-600V
AC, surge current capacity ratings from 100kA to 800kA, and NEMA
4 or NEMA 4X enclosures.
The Eaton SPD Max Series is available in two feature packages
(Basic and Standard with Surge Counter), as described in
Section 3,

. Each model is available in Delta, Wye, and Split
Phase wiring configurations.
All Eaton SPD Max Series models have been tested and certified
by Underwriter’s Laboratory (UL®), to comply with UL Standard
1449, 4th Edition, UL Standard 1283 7th Edition, CSA 22.2 and CSA
Electrical Notice NO. 516 Edition 1. This device can be used for
UL96A and NFPA 780 Compliance.

1.4 Catalog Numbering System
Each Eaton SPD Max Series unit has a name plate 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 5.

Feature Package
For example, a 480 volt Delta (3-wire plus Ground) for use in a
NEMA 4 application requires an SPD model SPM250480D2R,
where:
SPM
= SPD Max Series,
250
= the kA rating (100 – 800 kA),
480D
= the voltage,
3
= the feature package (Standard With Surge Counter),
R
= the 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
