Eaton SPD Series
Surge Protective Device for Integrated Units
1.0 Introduction
1.1 Manual Organization
This Installation Manual describes the safe installation, testing
and operation of the Eaton ® SPD Series Surge Protective Device
(SPD).
This manual is organized into seven sections, as follows:
1.0 Introduction
2.0 Installation
3.0 Operating Features
4.0 Troubleshooting
5.0 Specifications
6.0 Ordering Guidelines
7.0 Warranty
1.2 Product Overview
The Eaton SPD Series protects critical electrical and electronic
equipment from damage by power surges. This is done by
shunting high energy lightning surges (and other transient dis-
turbances) 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 Series is designed to mount on Panelboards,
Switchgear, Switchboards, Busway, and Motor Control Centers
(MCCs). It is available with surge current capacity ratings from
50 to 400kA.
The Eaton SPD Series is available in three feature pack-
ages (Basic, Standard, and Standard with Surge Counter), as
described in Section 3, "Operating Features." Each model is
available in Delta, Wye, and Split Phase wiring configurations.
All Eaton SPD Series models have been tested and certified by
Underwriter’s Laboratory (UL
®
), to comply with UL Standard
1449, 3 rd Edition.
1.3 Safety Precautions
A licensed/qualified electrician must complete all instructions
in this manual in accordance with the National Electric Code
(NEC
®
), state, and local codes, or other applicable country
codes. All applicable local electrical codes supersede these
instructions.

1.4 Catalog Numbering System
Each Eaton SPD 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.
Table 1. Catalog Numbering System
SPD 250 480D 2 J
For example, a 480 volt Delta (3-wire plus Ground) for use in
an MCC application requires an SPD model SPD 250480D2J,
where:
SPD = SPD model,
250 = the kA rating (50 – 400 kA),
480D = the voltage,
2 = the feature package (Basic, Standard, Standard With Surge
Counter), and,
J = the Application Suffix (such as Direct Bus Mounted in a
panelboard or Connected Through a Circuit Breaker).
These numbers appear as part of the product label attached to
the front left side of the SPD. See Figure 1.
