VAL-SQ SE…
120, 160 and 200 kA Service Entrance protection
Data Sheet
2460_en_B
2
The VAL-SQ SE… Surge Protective Device (SPD) provides
maximum surge protection for the service entrance. These
units are available with 120, 160 and 200 kA surge current
ratings to protect electronic equipment in industrial, medical
and commercial applications.
–
The VAL-SQ SE… utilizes a hybrid suppression circuit, Sine
Wave Tracking, in a single, replaceable module. It provides
both transient protection and up to -30 dB of noise filtration.
Each surge suppression mode is individually fused.
–
The product is provided in a NEMA Type 1 metal enclosure
and includes a function monitor.
–
120, 160 or 200 kA surge current capacity per phase
(L-N and N-G) protects against high-energy lightning
strikes
LEDs provide continuous feedback on the status of
each phase
Suppression status alarm sounds if protection is not
active due to a fault
Dry contacts allow connection to a remote monitoring
system
Sine Wave Tracking filter for increased equipment
protection
LCD counter displays the number of surges safely
taken to earth-ground
Replaceable modules available in the event of damage
UL/cUL listed; meets UL 1449 2nd edition February

Installation
The SPD can be mounted in any orientation.
DANGER:
2.
Turn off all power supplying this equipment
before working on or inside equipment.
Always follow federal and local regulations during
installation. Apply appropriate personnel
protective equipment (PPE) and follow electrical
work practices.
Secure the VAL-SQ SE… to the wall with the
appropriate type of fasteners, 2, (not included) for the
mounting surface, i.e., lag bolts for concrete surface,
metal screws for metal surface, etc. The enclosure
mounting holes are sized for 1/4 in. (6 mm) mounting
hardware.
NOTE:
Only qualified electrical personnel may install and
service this equipment.
3.
Remove the four screws, 3, securing the cover.
Disconnect the connector wire between the keypad in
the cover and the module and set the front cover aside.
s.
This equipment depends upon an effective
ground. Failure to obtain a quality ground
connection may result in explosion or arc flash.
co
WARNING:
m
Always secure the SPD to a mounting surface. Do
not rely on the conduit to hold the VAL-SQ SE….
NOTE:
6.1
Mounting and connection
ne
Position the VAL-SQ SE… as close as possible to the
service entrance being protected so the wires are as
short and straight as possible. LEDs must be visible and
the keypad accessible.
2
Cover or remove components inside any
enclosure before drilling to prevent shavings from
causing short-circuits across terminals and races.
4.
5.
Drill or punch an appropriate size hole(s) in the side of
the SPD for conduit attachment. The hole must match
the size of conduit used. Secure conduit with strain
relief nut.
Connect the VAL-SQ SE… to the power as shown on
the appropriate connection diagram.

for the SPD to function correctly. Conductors and circuit
breakers must be sized for the current load, typically
30 A minimum. Use an appropriate breaker, i.e., 2- or 3pole, for the electrical configuration.
The wires between the SPD and protected device
should be twisted 1/2 turn every 12 in. (300 mm).
Do not loop or coil wire. Excess wire must be
removed without applying stress to wires.
7.
In addition to the LEDs, an audible alarm sounds when a
fault is detected and the SPD is not providing full protection.
The audible alarm can be turned on and off by pressing the
alarm button, 3. When a fault occurs, press the alarm button
to turn the audible alarm off. If the alarm is off when a fault
occurs, the alarm is muted until the button is pressed again.
Ensure the ground (green) wire from the SPD is
attached to a solid earth ground.
Torque connection terminals to 35 lbf-in. (3.96 N•m)
and ground terminal to 50 lbf-in. (5.65 N•m).
When a phase LED is not lit, verify the correct voltage is
present on each phase. If power is present, the module must
be replaced.
co
DANGER:
Never apply power to the SPD with the cover
removed.
s.
A counter displays the number of transient voltage surges
detected since the counter was reset. The reset button is
located on the module inside the SPD.

fasteners previously removed.

When the VAL-SQ SE… is connected in a singleor split-phase configuration, only the ØA and ØC
LEDs and switches are present.

6.
If a phase is not operating correctly or a fault occurs, the
corresponding LED to that phase illuminates red.
The counter is battery powered to retain memory in the
event of power loss.
7.1
Testing operation
To test the integrity of the SPD diagnostics, each phase has
a button. With power applied, press the button for the
corresponding phase. If operating correctly, the phase LED
will change from green to red and the alarm will sound, if
enabled. When the button is released, the audible alarm will
stop and the LED will change back to green.
If the system fails the diagnostic test in any way, or one or
more of the phase LEDs illuminates red at power up, the
module must be replaced.
on
Phase LEDs, 1, indicate the operating status of the
individual phases of the VAL-SQ SE… The LEDs illuminate
green when the relevant phase is operating correctly.
Always remove power to the SPD before
removing the cover.
