Introduction
The QOSPD20 Surge Protective Device (SPD) is
designed to fit in a single pole circuit breaker space. It fits
all Square D™ brand QO load centers and is designed for
surge suppression of 230 V single phase, three-wire,
50 Hz electrical services and appliances.
Note: Use on solidly grounded systems only.
Precautions
DANGER /
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR
ARC FLASH
• Apply appropriate personal protective equipment (PPE)
and follow safe electrical work practices.
• This equipment must only be installed and serviced by
qualified electrical personnel.
• Turn off all power supplying this equipment before
working on or inside equipment.
• Always use a properly rated voltage sensing device to
confirm power is off.
• Replace all devices, doors and covers before turning on
power to this equipment.
Failure to follow these instructions will result in death
or serious injury.

WARNING /
INADEQUATE GROUNDING HAZARD
Do not use on ungrounded systems.
Failure to follow these instructions can result in
death or serious injury.
/
LOSS OF SURGE SUPPRESSION
• Do not energize the Surge Protective Devices until
the electrical system is completely installed,
inspected, tested, and all conductors have been
connected and functional, including the neutral.
• Verify the voltage rating of the Surge Protective
Device and electrical system before energizing the
electrical system.
• Perform high-potential insulation testing, or any other
testing, where the Surge Protective Device
components will be subjected to voltages higher than
their maximum continuous operating voltage (MCOV),
with the neutral and the Surge Protective Device
disconnected from the power source.
Failure to follow these instructions can result in
equipment damage.
Installation
1. Turn off all power to the load center before working
on or inside the equipment.
2. Remove the cover from the load center.
3. Install the SPD as shown in Figure 1. Ensure that
the SPD jaws fully engage the bus.
4. Replace the load center cover.
5. Energize the equipment. Verify that the indicator
lamp on the SPD illuminates. See Figure 2.
