Precautions

WARNING

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.

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.

Do not touch the load terminal of the G3PB immediately after
the G3PB is turned OFF, otherwise an electric shock may be
received due to the residual charge of the built-in snubber cir-
cuit.

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.

The built-in capacitor will be charged as long as power is sup-
plied. Do not touch the terminals of the G3PB unless the G3PB
is turned OFF and the built-in capacitor discharges all of its re-
sidual voltage, otherwise an electric shock may result.

Caution

Do not apply excessive voltage or current to the input or output
circuit of the G3PB, otherwise the G3PB may malfunction or
burn.

Do not use the G3PB unless all the output terminal screws are
tightened securely, otherwise the terminals may generate ex-
cessive heat and the G3PB may burn.

Be sure to provide enough ventilation to the G3PB and the ra-
diator, otherwise the G3PB may generate excessive heat and
the G3PB may burn or the output element may short-circuit.

Be sure to turn OFF the power supply to the G3PB before wir-
ing, otherwise an electric shock may be received.

Be sure to wire or solder the terminals of the G3PB properly,
otherwise the G3PB may generate excessive heat and burn.

If the G3PB is mounted directly to a control panel that is used
as a radiator as well, the control panel must be made of alumi-
num or a steel plate with low thermal resistance.
Do not use any material with high thermal resistance, such as
a wooden plate, otherwise the G3PB may catch on fire or burn.

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 take into consideration the dispersion
of the characteristics between G3PB Units.

•

The ratings in this datasheet 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 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.
For direct mounting, firmly mount the Relay on the panel.

Vertical Mounting

Horizontal Mounting

Vertical mounting

Panel

Note:

Make sure that the load current is 50% of the rated load cur-
rent when the G3PB is mounted horizontally.

Close Mounting

60 mm

30 mm

Note:

Be sure to provide a minimum space of 30 mm horizontally
and 60 mm vertically between adjacent Units.

WIRING

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

Output terminal section

Input terminal section

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 appropriate
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 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
malfunctioning.

MOUNTING MODELS WITHOUT BUILT-IN
HEAT SINK

Before attaching an external radiator or Heat Sink to the Unit, be
sure to apply silicone grease for heat radiation, such as
Toshiba’s YG6260 or Sinetsu Silicone’s G746, to the surface
where the radiator or Heat Sink is attached.

Be sure to apply the following torque to secure the Unit and external
radiator or Heat Sink for proper heat radiation.

Tightening torque: 2.0 N

OPERATING CONDITIONS

Do not apply current exceeding the rated current. Otherwise the
temperature of the Unit may rise excessively.

Be sure to prevent ambient temperature rising due to the heat radi-
ation of the Unit. In the case of enclosed mounting, install a fan so
that the interior of the panel can be fully ventilated.

OPERATING AND STORAGE
ENVIRONMENTS

Do not use or store the Unit in the following places, otherwise the
Unit may malfunction or the characteristics of the Unit may deterio-
rate.

•

Locations subject to direct sunlight.

•

Locations subject to ambient operating temperatures outside
the range of –30

C to 80

•

Locations subject to ambient operating humidity outside the
range of 45% to 85%.

•

Locations subject to condensation as the result of severe
changes in temperature.
