Transient Voltage Surge Suppression
Installation Instructions
SES 200 Series
Series utilizes Transient Discriminating™ (TD)
technology. Not only does this meet the safety
standards of UL 1449 Edition 2, but provides a superior
life by eliminating the common temporary overvoltage
failure mode of most SPDs.

entrance panel applications
• NEMA Type 4/4X/12/13 enclosure
• Internal high interrupt capacity fusing for added
safety
• Modular design allows easy replacement of surge
modules
• Transient Discriminating™ (TD) technology for long
service life. Ideal for sites with poor voltage
regulation
• Combination MOV and SAD protection
APPLICATION
ERICO's SES 200 Series of Transient Voltage Surge
Suppressors has been designed to deliver specification
grade performance and features at an affordable price.
The versatile and compact design provides high quality
protection for a wide variety of commercial and industrial
applications where sensitive electronic equipment is to
be protected.
The SES provides a service life equivalent to up to
200kA, 8/20µs per line of surge material, making it ideal
for the protection of service entrance panels and
ensuring a long operational life under severe lightning
conditions. Internal electronics continuously monitor
SPD protection, and the status of each mode of
protection is displayed on a 5-segment LED bar graph.
Alarm contacts for remote monitoring is provided as
standard.
The replaceable surge modules provide protection to LN and N-G modes, ensuring effective protection from
both common mode and differential transients.
Following ERICO's position as a supplier of quality
lightning and surge protection solutions, the SES 200
PREPARATION
DANGER: Electrical shock or burn hazard. The
installation of this Transient Voltage Surge Suppressor
should be made by qualified personnel. Failure
to lockout electrical power during installation or
maintenance can result in fatal electrocution or
severe burns.
CAUTION: Check to make sure line voltage does not
exceed Surge Protector voltage requirement. This
system is designed for 120/240 1-phase or
120/208V or 277/480V 3-phase systems.
CAUTION: This unit must be installed in accordance with
the National Electrical Code (ANSI/NFPA-70) and
applicable local codes, and must be installed on the load
side of the main overcurrent protection.
These instructions should be read in their
entirety before commencing installation.
PRIOR TO INSTALLATION
Confirm that the voltage system rating as shown on the
SES 200 label located on inside of the enclosure is
appropriate for the intended application.

DISCONNECT / LOCKOUT POWER
Disconnect and lockout power to the point where the
SES 200 is to be installed. Follow all applicable
electrical codes and safe working practices.
INSTALLATION
PHYSICAL LOCATION
1. The SES 200 should be installed as close as
possible to the service switchboard, switchgear,
power distribution panelboard or other determined
connection point. The location should be chosen to
keep the interconnecting wiring as short as possible.
Any sharp bends in the wiring should be avoided.
ENCLOSURE MOUNTING
2. The SEP 200 should be mounted utilizing the four
mounting holes provided as part of the enclosure.
Mount the SES 200 securely and rigidly to the
surface or structural member.
CONDUIT HOLE LOCATION

tighten to a torque of 35 in-lbs.

3. The conductors should exit the enclosure at the top
of the enclosure above the wiring terminals. The
hole should be sized appropriately for the desired
conduit fittings. If the conductors are required to exit
the enclosure through the top wall, the hole should
be placed directly above the terminals. If the
enclosure is being located directly adjacent to a
panelboard, the hole should be placed on the right
or left side of the enclosure within 2” of the top. A
straight nipple may be used; otherwise an
appropriate conduit connector should be used.
If remote alarming is required, an additional hole
may need to be made for connection to the alarm
contacts.
WIRING DIAGRAM
4. The wiring diagrams below show how the SES 200
is to be wired. This TVSS device is wired in parallel
with the distribution system be protected. The SES
200 is supplied with a fuse holder with integral
overcurrent protection. Additional external
overcurrent protection is not necessary.
The recommended wire size for the SES 200 Series
TVSS is #6 AWG and a #6 AWG ground. When
terminating the wiring on the SES terminals, strip the
Figure 2. SES 200 Single-Phase Wiring Diagram
INDICATORS
5. The SES 200 has TDS-MOVTECs as the TVSS
elements. Each of these MOVTECs has a 5 LED
bar graph arranged so that they are visible through
the front of the enclosure. When all 5 LEDs on each
MOVTEC are illuminated, the protection circuitry is
operating correctly for that line. If one LED has
extinguished, the Surge Protector has sustained a
surge, which has reduced the remaining capacity,
and the protection has been compromised. If two
LEDs are extinguished, the surge capacity has been
reduced to 60% of total capacity. The alarm relay
will drop out at this point. While there is still some
protection provided, the Surge Protector should be
replaced as soon as possible.

EXTERNAL ALARM
6. Each of the blue TDS-MOVTEC units inside the
SES 200 unit provides an alarm relay contact
indicating its status. These contacts are wired to the
X5 and X7 terminals on top of the unit. When the
unit is correctly powered and operational, the relay
will be operated and these two terminals will be
connected together. If power is removed from the
unit or the MOVTEC module becomes damaged due
to excessive surge energy, the relay contacts will
open.
To provide external alarm indication from the unit,
the two alarm contacts from each MOVTEC are
connected in series. That is, for the single-phase
unit with 3 MOVTECs, the external alarm wiring is
connected to “X5 MOVTEC 1” and “X7 MOVTEC 3”.
A small interconnecting link of the same wiring type
is connected from (“X7 MOVTEC 1” to “X5 MOVTEC
2”) and from (“X7 MOVTEC 2” to “X5 MOVTEC 3”).
Connection is made to the terminals by depressing
the orange tab, inserting a stripped wire (22 AWG –
16 AWG) and releasing the orange tab. These
contacts are rated at 2A, 30Vdc; 0.6A, 110Vdc;
0.6A, 125Vac. For the three-phase units, ensure the
4th MOVTEC is wired in series in the same manner.
ENGAGING POWER
7. Verify all wiring connections, replace the enclosure
door lid and engage power feeding the SES 200. All
MOVTEC surge module bar graphs should be
illuminated.
REPLACEMENT OF TDS-MOVTECS
Should a TDS-MOVTEC module require replacement,
they are designed to be replaceable in the field by a
Licensed Electrical Contractor, following the steps
below:
1. Identify the module to be replaced, and obtain a
replacement module. Confirm that the replacement
module is the same model number and is designed
for the same voltage.
2. Disconnect and lockout power to the SES 200.
Follow all applicable electrical codes and safe
working practices.
3. Unscrew the wired terminals on the module to be
replaced and carefully remove the wiring from the
module, noting where each wire is connected.
4. Remove the module to be replaced from the back
panel.
5. Install the replacement module in place, again
checking that it is the same part number as the
faulty module.
6. Replace the wiring into the correct terminals,
tightening each terminal to a torque of 13 in-lb.
7. Verify all wiring connections, close the SEP
enclosure door and engage power to the system.
8. All MOVTEC surge module protection indicators
should all be illuminated.
MAINTENANCE
This unit requires no regular preventative maintenance,
apart from periodically observing the indicators to verify
continued correct operation.
If any of the status LEDs are not illuminated,
disconnect power, check wiring, rectify any
deficiencies, and re-power the unit. If still
experiencing difficulties, please contact your supplier
or the manufacturer.
