1 Introduction
1.1 Manual introduction
This installation manual describes the installation and operation of
the Eaton SPC series surge protective device (SPD) . This techni-
cal document covers most aspects of installation and operation .
This document is a guide only for licensed/qualified electricians . If
you require further information regarding a particular installation,
application, or maintenance activity, please contact your Eaton rep-
resentative . These instructions do not cover all details, variations or
combinations of the equipment, its storage, delivery, installation,
check-out, safe operation or maintenance . Care must be exercised to
comply with local, state, and national regulations, as well as safety
practices for this class of equipment .
Please read and understand ALL installation and operating
instructions prior to installation and use of this equipment.
1.2 Product overview
The Eaton SPC series protects critical electrical and electronic equip-
ment from damage by voltage transients and surges when properly
installed . 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 through thermally protected metal oxide varistors while
supporting power frequency voltage . Eaton’s Type 2 SPC models
equipped with EMI Filtering are designed to protect sensitive equip-
ment from electrical noise . Proper installation is critical to ensure
the SPC operates as intended .
Eaton’s Type 1 SPC is intended for installation between the sec-
ondary of the service transformer and the line side of the service
equipment overcurrent device . As well as the load side, including
watt-hour meter socket enclosures and Molded Case surge protec-
tive devices intended to be installed without an external overcurrent
protective device .
Eaton’s Type 2 SPC is intended for installation on the load side of the
service equipment overcurrent device . Including branch panel loca-
tions and functions to protect sensitive electronic equipment from
damaging voltage transients and surges .
The SPC should be installed as close as possible to the equipment
to be protected .
The SPC series is available in voltage ratings from 120 Vac to
600 Vac, surge current ratings from 50kA to 200kA, and two sizes
of Type 4X enclosures . Enclosure size is determined by voltage
and peak surge current rating . The P1 enclosure measures 6 .00” x
5 .56” x 3 .19” (152 .3 mm x 141 .2 mm x 81 .1 mm) with a maximum
weight of 2 .5 lbs (1 .13 kg) . The P2 enclosure measures 8 .50” x
7 .56” x 3 .19” (215 .9 mm x 192 .0 mm x 81 .1 mm) with a maximum
weight of 4 .15 lbs (1 .81 kg) .
The Eaton SPC series is available in eight feature options, see
Section 10, Ordering guidelines
for more details .
1.3 Safety precautions
WARNING
WARNING – SHOCK HAZARD – DO NOT OPEN.
AVERTISSEMENT – RISQUE DE CHOC – NE PAS OUVRIR.
WARNING NO SERVICEABLE PARTS.
ATTENTION : AUCUNE PIÈCE REMPLACABLE OU RÉPARABLE.
A LICENSED/QUALIFIED ELECTRICIAN MUST COMPLETE ALL
INSTRUCTIONS IN THIS MANUAL IN ACCORDANCE WITH THE NATIONAL
ELECTRIC CODE (NEC), CANADIAN ELECTRICAL CODE (CEC), STATE, AND
LOCAL CODES, OR OTHER APPLICABLE COUNTRY CODES. ALL APPLICABLE
LOCAL ELECTRICAL CODES SUPERSEDE THESE INSTRUCTIONS.
CHECK THE VOLTAGE-RATING LABEL LOCATED ON THE SIDE OF THE SPC
TO VERIFY THAT THE ELECTRICAL SYSTEM’S VOLTAGE AND WIRING
CONFIGURATION ARE THE SAME AS THE SPC.
CONDUCTING DIELECTRIC, MEGGAR, OR HI-POTENTIAL TESTING WITH
THE SPD INSTALLED WILL CAUSE INTERNAL DAMAGE TO THE SPD. THE
SPD WILL CAUSE THE TEST TO FAIL.
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.
ARC FLASH DURING INSTALLATION COULD CAUSE INJURY OR DEATH.
USE APPROPRIATE SAFETY PRECAUTIONS AND EQUIPMENT FOR ARC
FLASH PROTECTION.
INSTALLING A PROTECTION DEVICE WHICH IS UNDER RATED FOR THE
ELECTRICAL SYSTEM VOLTAGE CAN CREATE A POTENTIALLY HAZARDOUS
CONDITION.
CHECK THE FACILITY’S GROUNDING SYSTEM. ALL GROUNDING, BONDING
AND EARTHING PRACTICES MUST MEET NEC, CEC AND LOCAL APPROVED
PRACTICES. A POOR GROUND, OR A GROUNDING / BONDING VIOLATION
WILL SERIOUSLY AFFECT THE SPD’S ABILITY TO FUNCTION AS SPECIFIED.
