Preventing Overheating with a High-
capacity Heat Sink (Y92B-P250NF)
• When the High-capacity Heat Sink is used, high-capacity switching
• If the Fan stops due to a power supply error, due to foreign matter
• A thermostat is provided to detect overheating. The thermostat
• Do not connect the thermostat directly to the load power supply.
• Terminals equivalent to Faston #187 are used for the thermostat
• Do not place heat-dissipating silicon grease on the thermostat.
• Do not solder the thermostat terminals.

Noise Terminal Voltage According to
EN55011
The G3NA-UTU complies with EN55011 standards when a capacitor
is connected to the load power supply as shown in the following cir-

This thermostat can be used to stop the operation of the SSR.
Implement an overheating prevention measure by using this signal
to output an alarm or perform another response applicable to the
system. Also, confirm that there is no problem with the overall sys-

Loss Time
The loss time will increase when the G3NA is used at a low applied
voltage or current. Be sure that this does not cause any problems.
Using DC Loads
For a DC or L load, a diode should be connected in parallel the load
to absorb the counter electromotive force of the load.
Fuses
Connect a quick-break fuse in series with the load as a short-circuit
protection measure. Use one of the fuses in the following table or one
with equivalent or better characteristics.
Recommended Fuses
Reverse Connection
The output terminal side of the G3NA-D210B is connected to a built-
in diode to protect 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. Therefore, pay the
utmost attention not to make polarity mistakes on the load side.
