adversely affected.
Meaning of Graphic Symbols for Ensuring Product Safety
Indicates the possibility of electric shock under
specific conditions.
Indicates the possibility of explosion under specific
conditions.
Indicates the possibility of injuries by high
temperature under specific conditions.
Precautions for Safe Use
OMRON constantly strives to improve quality and reliability.
The G3PJ, however, use semiconductors, and semiconductors may
commonly malfunction or fail. In particular, it may not be possible to
ensure safety if the G3PJ are used outside the rated ranges.
Therefore, always use the SSRs within the ratings. When using the
G3PJ, always design the system to ensure safety and prevent human
accidents, fires, and social harm in the event of the G3PJ failure.
System design must include measures such as system redundancy,
measures to prevent fires from spreading, and designs to prevent
malfunction.
Transport
Do not transport the G3PJ under the following conditions.
Doing so may result in damage, malfunction, or deterioration of
performance characteristics.
• Conditions in which the G3PJ may be subject to water.
• Conditions in which the G3PJ may be subject to high temperature
or high humidity.
• Conditions in which the G3PJ is not packaged.
• Do not drop the G3PJ or subject it to abnormal vibration or shock
during transportation or mounting. Doing so may result in
deterioration of performance, malfunction, or failure.
Operating and Storage Environments
CAUTION
Minor electrical shock may occasionally occur.
Do not touch the G3PJ terminal section (i.e., currentcarrying parts) while the power is being supplied.
Also, always attach the cover terminal.
The G3PJ may rupture if short-circuit current flows. As
protection against accidents due to short-circuiting,
be sure to install protective devices, such as fuses
and no-fuse breakers, on the power supply side.
Minor electrical shock may occasionally occur.
Do not touch the main circuit terminals on the G3PJ
immediately after the power supply has been turned
OFF. Shock may result due to the electrical charge
stored in the built-in snubber circuit.
Minor burns may occasionally occur.
Do not touch the G3PJ or the heat sink while the
power is being supplied or immediately after the
power supply has been turned OFF. The G3PJ and
heat sink become extremely hot.
Do not use or store the G3PJ in the following locations. Doing so may
result in damage, malfunction, or deterioration of performance
characteristics.
• Locations subject to rainwater or water splashes.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to high temperature or high humidity.
• Do not store in locations subject to ambient storage temperatures
outside the range −30 to 100°C.
• Locations subject to relative humidity outside the range 35% to
85% or locations in which condensation may occur due to rapid
changes in temperature.
• Locations subject to corrosive gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to direct sunlight.
• Locations subject to shock or vibration.
• Do not allow solvents such as thinners or gasoline to come into
contact with the plastic parts of the G3PJ. A solvent may erase the
markings.
• Do not allow oil to come into contact with the terminal cover on the
G3PJ. The cover may become milky or crack.
Installation and Handling
• Do not block the movement of the air surrounding the G3PJ or heat
sink. Abnormal heating of the G3PJ may result in shorting failures
of the output elements or burn damage.
• Do not use the G3PJ if the heat radiation fins have been bent by
being dropped. Doing so may result in malfunction due to a
reduction in the heat radiation performance.
• Do not handle the G3PJ with oily or dusty (especially iron dust)
hands. Doing so may result in malfunction.

G3PJ
Installation and Mounting
Installation and Usage
• Mount the G3PJ in the specified direction. (Refer to Mounting on
page 7.) Excessive heat generated by the G3PJ may cause shortcircuit failures of the output elements or burn damage.
• Make sure that there is no excess ambient temperature rise due to
the heat generation of the G3PJ. If the G3PJ is mounted inside a
panel, install a fan so that the interior of the panel is fully ventilated.
• Make sure the DIN track is securely mounted. Otherwise, the G3PJ
may fall.
• When mounting the heat sink, do not allow any foreign matter
between the heat sink and the mounting surface. Foreign matter
may cause malfunction due to a reduction in the heat radiation
performance.
• If the G3PJ is mounted directly in a control panel, use aluminum,
steel plating, or similar material with a low heat resistance as a
substitute for a heat sink. Using the G3PJ mounted in wood or
other material with a high heat resistance may result in fire or
burning due to heat generated by the G3PJ.
• The G3PJ is heavy. Firmly mount the DIN track and secure both
ends with End Plates for DIN-track-mounting models. When
mounting the G3PJ directly to a panel, firmly secure it to the panel.
Installation and Wiring
• Use wires that are suited to the load current. Otherwise, excessive
heat generated by the wires may cause burning.
• Do not use wires with a damaged outer covering.
Otherwise, it may result in electric shock or ground leakage.
• Do not wire any wiring in the same duct or conduit as power or
high-tension lines. Otherwise, inductive noise may damage the
G3PJ or cause it to malfunction.
• When tightening terminal screws, prevent any non-conducting
material from becoming caught between the screws and the
tightening surface. Otherwise, excessive heat generated by the
terminal may cause burning.
• Do not use the G3PJ with loose terminal screws. Otherwise,
excessive heat generated by the wire may cause burning.
• Use suitable wire lengths for wiring. Inductive noise may
occasionally cause malfunction, failure, or burn damage.
• Always turn OFF the power supply before performing wiring. Not
doing so may cause electrical shock.
Push-In Plus Terminal Block
• Do not wire anything to the release holes.
• Do not tilt or twist a flat-blade screwdriver while it is inserted into a
release hole on the terminal block. The terminal block may be
damaged.
• Insert a flat-blade screwdriver into the release holes at an angle.
The terminal block may be damaged if you insert the screwdriver
straight in.
• Do not allow the flat-blade screwdriver to fall out while it is inserted
into a release hole.
• Do not bend a wire past its natural bending radius or pull on it with
excessive force. Doing so may cause the wire disconnection.
• Do not insert more than one wire into each terminal insertion hole.
• To prevent wiring materials from smoking or ignition, use the wiring
materials given in the following table.
Recommended Wire
0.25 to 1.5 mm2 / AWG24 to AWG16

• Do not apply a voltage or current that exceeds the rating to any
terminal. Doing so may result in malfunction or burn damage.
• Select a load within the rated values. Not doing so may result in
malfunction, failure, or burning.
• Select a power supply within the rated frequencies. Not doing so
may result in malfunction, failure, or burning.
• If a surge voltage is applied to the load of the Contactor, a surge
bypass(*) will function to trigger the output element. The G3PJ
therefore cannot be used for motor loads. Doing so may result in
load motor malfunction.
* Surge Bypass
This circuit protects the output circuit from being destroyed. This
suppresses the surge energy applied inside the SSR in comparison
with a varistor for the main circuit protection. By alleviating electrical
stress on the electronic components of the SSR's output circuit,
failure and destruction due to surge voltage are suppressed.
Reference value: Surge dielectric strength of 30 kV min.
(Test conditions: 1.2 ✕ 50 μs standard voltage waveform, peak voltage
of 30 kV, repeated 50 times according to JIS C5442)
Precautions for Correct Use
The G3PJ in operation may cause an unexpected accident.
Therefore it is necessary to test the G3PJ under the variety of
conditions that are possible. As for the characteristics of the G3PJ, it
is necessary to consider differences in characteristics between
individual G3PJ.
The ratings in this catalog are tested values in a temperature range
between 15°C and 30°C, a relative humidity range between 25% and
85%, and an atmospheric pressure range between 86 and 106 kPa.
It will be necessary to provide the above conditions as well as the load
conditions if the user wants to confirm the ratings of specific SSRs.

Repetition period: 100 Hz
Noise application time: 3 min
Mounting to Control Panel
If the panel is airtight, heat from the G3PJ will build up inside, which
may reduce the current carry ability of the G3PJ or adversely affect
other electrical devices. Be sure to install ventilation holes on the top
and bottom of the panel.

Air inlet
Note: 1. If the air inlet or air outlet has a filter, clean the filter regularly
to prevent it from clogging to ensure an efficient flow of air.
2. Do not locate any objects around the air inlet or air outlet,
otherwise the objects may obstruct the proper ventilation of
the control panel.
3. A heat exchanger, if used, should be located in front of the
G3PJ to ensure the efficiency of the heat exchanger.
G3PJ Ambient Temperature
The rated current of the G3PJ is measured at an ambient temperature
of 40°C.
The G3PJ uses a semiconductor to switch the load. This causes the
temperature inside the control panel to increase due to heating
resulting from the flow of electrical current through the load. The G3PJ
reliability can be increased by adding a ventilation fan to the control
panel to dispel this heat, thus lowering the ambient temperature of the
G3PJ.
(Arrhenius's law suggests that life expectancy is doubled by each
10°C reduction in ambient temperature.)

Example: For 10 G3PJ with load currents of 15 A,
0.23 × 10 = 2.3
Thus, 3 fans would be required.
Note: 1. Size of fans: 92 mm × 92 mm, Air volume: 0.7 m3/min,
Ambient temperature of control panel: 30°C
2. If there are other instruments that generate heat in the
control panel in addition to the G3PJ, more ventilation will
be required.
3. Ambient temperature: The temperature that will allow the
G3PJ to cool by convection or other means.
