Eaton SP1

Surge Protective Device (SPD)

Reliable, Cost-Effective
Surge Protection

Introduction

Eaton‘sT SP1 is a ULT 1449 3rd Edition-listed surge protective
device that provides reliable, cost-effective surge protection.
This Type 1 SPD is capable of being installed on either the
line or load side of the service entrance disconnect and can
be used as a replacement for devices formerly known as
secondary surge arrestors or lightning arrestors, which could
not be manufactured after UL 1449 3rd Edition went into
effect on September 29, 2009. The unit is available in many
common voltages and configurations. Multiple mounting
options coupled with a compact footprint enables installation
of the SP1 in a wide range of applications, including panel­boards, loadcenters, pump panels, control cabinets, and other
electrical assemblies and applications.

Installation and Operation

Installation and operation of the
SP1 is simple. The unit comes
pre-wired with 24 inches of
10-gauge wire and is mounted
via the ½" nipple that is molded
into its enclosure. Wall or DIN­rail mounting can also be accom­plished with the addition of an
optional kit. When powered, the
unit‘s light-emitting diode (LED)
indicator reports the status of
the protection elements and
is active when all of them are
intact and providing protection.
Any loss of protection is
signaled when the LED
extinguishes.
