Eaton SPD Series
Surge Protective Device for Integrated Units
3.0 Operating Features
3.1 General
The Eaton SPD Series comes in three feature packages: Basic,
Standard, and Standard with Surge Counter. The operating spe-
cifics of each feature package are described below.
The Eaton SPD Series requires no operator involvement, other
than to monitor the display panel to determine status of the
SPD.
After system power is applied, the SPD automatically begins
protecting downstream electrical equipment from voltage tran-
sients.
Some SPD units have a Form C relay contact that allows for the
remote indication of SPD status. Form C contact wires are con-
nected via a three terminal connector. See Figure 13.
3.2 Displays and Indicators
All Eaton SPD Series units (Basic, Standard, and Standard With
Surge Counter) use a display panel to indicate system status.
The display panel is slightly different for each feature package.
Each display has both green and red light emitting diodes
(LEDs) to indicate the status of the protection on each phase.
Green indicates the phase is fully protected. Red indicates a
loss of protection. Wye, Split Phase and High-Leg Delta units
have an additional set of green/red LEDs to indicate status of
Neutral/Ground protection.
When the LEDs turn red, an audible alarm will also sound on
units equipped with an audible alarm.
Specific operating conditions displayed for each Eaton SPD
Series Feature Package are described below.

•
Red LEDs: Illumination indicates a loss of protection, and
