Preventing Overheating with a
High-capacity Heat Sink (Y92B-P250NF)
? When the High-capacity Heat Sink is used, high-capacity switching
at 75 A or 90 A requires forced cooling with a fan. Connect the Fan
to a power supply according to its ratings specifications.
? If the Fan stops due to a power supply error, due to foreign matter
in the power supply connection, or due to aging, the Heat Sink will
heat to high temperatures, possibly resulting in failure of the SSR or
adverse affects on other devices. Implement an overheating pre-
vention measure, such as turning OFF the load current, if the Heat
Sink overheats.
? A thermostat is provided to detect overheating. The thermostat uses a
NC contact, i.e., the circuit will be opened for overheating. This thermo-
stat can be used to stop the operation of the SSR. Implement an over-
heating 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 system.
? Do not connect the thermostat directly to the load power supply.
Connect it to a contactor or other shutoff device connected above
the SSR.
? Terminals equivalent to Faston #187 are used for the thermostat
terminals.
? Do not place heat-dissipating silicon grease on the thermostat.
? Do not solder the thermostat terminals.
? The following diagram shows a protective circuit example.

? The input cable must be less than 3 m.
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.

? Refer to Ventilation Outside the Control Panel .
Operating Conditions
? Do not apply currents exceeding the rated current otherwise, the
temperature of the G3NA may rise excessively.
? 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.
? Do not apply overvoltages to the input circuit or output circuit. Fail-
ure or burning may result.
? Do not drop the G3NA or otherwise subject it to abnormal shock.
Malfunction or failure may result.
? Keep the cooling system running continuously during the ON/OFF
operation of the SSR. This is to allow residual heat to dissipate
while the SSR is OFF. (load current 75A, 90A models)

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.
