Precautions
Do not touch the terminals (i.e., charged parts) of the G3PB
while power is supplied, otherwise an electric shock may be
received.
If the G3PB is provided with a terminal cover, be sure to attach
the terminal cover to the G3PB before operating the G3PB.
WARNING
WARNING
The G3PB and radiator are very hot while power is supplied to
the G3PB.
Do not touch the G3PB or the radiator while power is supplied
to the G3PB or immediately after the G3PB is turned OFF,
otherwise a burn may result.
WARNING
Do not touch main circuit terminal of the G3PB immediately af-
ter the G3PB is turned OFF, otherwise an electric shock may
be received due to the residual charge of the built-in snubber
circuit.
WARNING
Be sure to turn OFF the power supply to the G3PB before wir-
ing, otherwise an electric shock may be received.
Mount the terminal cover to the G3PB after wiring.
Do not touch the terminals of the G3PB while power is sup-
plied, otherwise an electric shock may be received.
WARNING
Ensure that a short-circuit current does not flow on the load
side of the SSR, otherwise the G3PB may be damaged.
J
General Precautions
At OMRON, we are constantly working to improve the quality and
reliability of our products. SSRs, however, use semiconductors,
which are prone to malfunction. Be sure to use SSRs within their
rated values.
Use the SSR only in systems that are designed with redundan-
cies, flame protection, counter measures to prevent operation
errors, and other countermeasures to prevent accidents involving
human life or fires.
1. Do not apply voltages or currents to the G3PB's terminals
in excess of the rated values. Doing so may result in
malfunction or burning.
2. Do not use the G3PB with terminal screws not properly
tightened. Abnormal heating of the terminals may result in
burning.
3. Do not obstruct the flow of air around the G3PB and the
radiator. Abnormal heating of the G3PB may result
short-circuiting of output elements and burning.
4. Perform wiring and tighten screws according to the
instructions given under Correct Use. Using the G3PB with
incorrect wiring or with the screws not tightened properly
may result in burning due to abnormal heating of the G3PB
during use.
J
Correct Use
Before Actual Operation
The G3PB in operation may cause an unexpected accident.
Therefore it is necessary to test the G3PB under a variety of
conditions that are possible. As for the characteristics of the
G3PB, it is necessary to consider differences in
characteristics between G3PB Units.
The ratings in this datasheet are tested values in a
temperature range between 15C and 30C, a relative
humidity range between 25% and 85%, and an atmospheric
pressure range between 88 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 actual G3PB Units.
Mounting Method
Since the Relay is heavy, firmly mount the DIN track and fix both
ends with End Plates for DIN-track-mounting models.
Applicable DIN Tracks
The G3PB can be mounted to TH35-15Fe (IEC60715) DIN
tracks. The manufacturers and models of DIN tracks to which
mounting is possible are shown in the following table.

Wiring
When using crimp terminals, refer to the terminal clearances
shown below.

Be sure that all lead wires are thick enough according to the
current.
Output terminals T1, T2, and T3 are charged regardless of
whether the Unit is a 2- or 3-element model that is turned on
or off. Do not touch these terminals, otherwise an electric
shock may be received.
To isolate the Unit from the power supply, install an appropri-
ate circuit breaker between the power supply and Unit.
Be sure to turn off the power supply before wiring the Unit.
Terminal L2 and terminal T2 of the 2-element model are
internally short-circuited to each other. Therefore, connect
terminal L2 to the ground terminal side of the power supply. If
terminal L2 is connected to a terminal other than the ground
terminal, cover all the charged terminals, such as heater
terminals, for the prevention of electric shock accidents and
ground faults.
Tightening Torque
Refer to the following and be sure to tighten each screw of the
Unit to the specified torque in order to prevent the Unit from mal-
functioning.

Operating Conditions
Do not apply current exceeding the rated current otherwise,
the temperature of the G3PB may rise excessively.
Be sure to prevent the ambient temperature rising due to the
heat radiation of the G3PB. If the G3PB is mounted inside a
panel, install a fan so that the interior of the panel is fully
ventilated.
Do not use the G3PB if heat dissipation fins have been bent
as a result of, for example, dropping the G3PB. If used in this
state, the G3PB may be damaged due to the decreased heat
dissipation capacity.
Only use the G3PB with loads that are within the rated values.
Using the G3PB with loads outside the rated values may
result in malfunction, damage, or burning.
Use a power supply within the rated frequency range. Using a
power supply outside the rated frequency range may result in
malfunction, damage, or burning.
Keep wiring separate from high-voltage power lines and use
wires of an appropriate length, otherwise malfunction and
damage may result due to induction.
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.

Operating and Storage Environments
Operating Ambient Temperature
The rated value for the ambient operating temperature of the
G3PB is for when there is no built-up heat. For this reason, under
conditions where heat dissipation is not good due to poor ventila-
tion, and where heat may build up easily, the actual temperature
of the G3PB may exceed the rated value resulting in malfunction
on burning.
When using the G3PB, design the system to allow heat dissipa-
tion sufficient to stay below the Load Current vs. Ambient Tem-
perature characteristic curve. Note also that the ambient temper-
ature of the G3PB may increase as a result of environmental
conditions (e.g., climate, air-conditioning) and operating condi-
tions (e.g., mounting in an airtight panel).
Operating and Storage Locations
Do not use or store the G3PB in the following locations. Doing so
may result in damage, malfunction, or deterioration of perfor-
mance characteristics.
Do not use or store in locations subject to direct sunlight.
Do not use in locations subject to ambient temperatures
outside the range --20 to 60C (--4F to 140F).
Do not use in locations subject to relative humidity outside the
range 45% to 85% or locations subject to condensation as the
result of severe changes in temperature.
Do not store in locations subject to ambient temperatures
outside the range --30 to 70C (--22F to 158F).
Do not use or store in locations subject to corrosive or
flammable gases.
Do not use or store in locations subject to dust (especially iron
dust) or salts.
Do not use or store in locations subject to shock or vibration.
Do not use or store in locations subject to exposure to water,
oil, or chemicals.
Transportation
When transporting the G3PB, observe the following points. Not
doing so may result in damage, malfunction, or deterioration of
performance characteristics.
Do not drop the G3PB or subject it to severe vibrations or
shock.
Do not transport the product if it is wet.
Vibration and Shock
Do not subject the SSR to excessive vibration or shock. Other-
wise the SSR may malfunction and internal components may be
damaged.
To prevent the SSR from abnormal vibration, do not install the
G3PB in locations or by means that will subject it to the vibrations
from other devices, such as motors.
Solvents
Do not allow the G3PB to come in contact with solvents such as
thinners or gasoline. Doing so will dissolve the markings on the
SSR.
Oil
Do not allow the G3PB terminal cover to come in contact with oil.
Doing so will cause the cover to crack and become cloudy.

Operation
Leakage Current
A leakage current flows through a snubber circuit in the G3PB
even when there is no input. Therefore, always turn OFF the
power to the input or load and check that it is safe before replac-
ing or wiring the G3PB.

Screw Tightening Torque
Tighten the G3PB terminal screws properly. If the screws are not
tight, the G3PB will be damaged by heat generated when the
power is ON.
Mounting
Do not perform mounting with oil or metal powder on your hands.
Doing so may result in damage to the G3PB.
Dropping
Be careful not to drop the G3PB during mounting. The G3PB
weighs approximately 1.25 to 2.0 kg and could cause injury if
dropped on any part of your body.
