Solid State Relay
G3NA
A Wide Range of Models with 5- to 40-A
Output Currents and Up to 480-VAC/
200-VDC Output Voltages
All models feature the same compact dimensions to provide
a uniform mounting pitch.
Built-in MOV effectively absorbs external surges.
Operation indicator (red LED) enables monitoring operation.
Protective cover for greater safety.
Standard models approved by UL/CSA.
AC and DC input versions available.
Ordering Information
To Order: Select the part number and add the desired rated input voltage, (e.g., G3NA-240B-100 to 120 VAC).
* Loss time increases under 75 VAC.
Note: 1. When ordering a TV-approved model, add "-UTU" to the model number as shown below:
Example: G3NA-210B-UTU.
2. VDE versions available. Contact your local OMRON representative.
3. G3NA-4 are not CE marked.
4. G3NA-2 with "-UTU" are CE marked.

G3NA
Heat Sink Size vs. Load Current
G3NA-220B
Note: The heat sink size refers to the combined area of the sides of the heat sink that radiate heat. For example, when a current of 18 A is allowed
to flow through the SSR at 40C, the graph shows that the heat sink size is about 450 cm
2
. Therefore, if the heat sink is square, one side of
the heat sink must be 15 cm (15
2
x 2 = 450) or longer.
Dimensions
In the case of surface mounting, a 30% derating of load current is required.

Precautions
See General Information Section near the back of this catalog for Solid State Precautions.
Load Connection
For an AC load, use a power supply rated at 50 or 60 Hz.
The maximum operating frequency is 10 Hz.
The G3NA has a built-in varistor for overvoltage protection.
Zero Cross Function
An SSR with a zero cross function operates when an AC load voltage
reaches the zero point or its vicinity. This reduces clicking noises
when the load is input, and minimizes the influence of an inductive
load, such as a lamp, heater, or motor, on the power supply because
the inrush current of the load is reduced. This can also minimize the
scale of the inrush current protection circuit.
At a low applied voltage, such as 24 VAC, the load current is not fully
supplied. When the Unit is switched ON, the voltage required to
power the Unit deprives the output signal of the necessary voltage
level and thus creates loss time. The lower the load voltage is, the
greater the loss time is. This condition, however, will not create any
serious problems.
For a DC or L load, a diode should be connected in parallel to the
load to absorb the counter electromotive force of the load.
When attaching a heat sink to the G3NA, apply Silicone Grease or
equivalent heat conductive grease on the heat sink. (Toshiba Silicon,
Shinetsu Silicon, etc.)
Tighten the mounting screws of the heat sink with a torque of 0.78 to
0.98 N

EN55011 Measurement of Mains
Terminal Disturbance Voltage
The G3NA-UTU conforms to EN55011 standards when a capacitor is
connected to the load power supply as shown in the following circuit
diagram.
Recommended Capacitor:
Nissei Denki's MKT-series R40 (1 F)
The output terminal side of the G3NA-D210B is connected to a built-
in diode for protecting the SSR from damage that may result from
reverse connection. The SSR, however, cannot withstand one minute
or more if the wires are connected in reverse order. Therefore, pay
the utmost attention not to make polarity mistakes on the load side.
