(5) G3PF and Duct (or Other Object Blocking Airflow)
Relationship
Incorrect Example
Duct or other object
blocking airflow
Countermeasure 1
30 mm max.
(No more than 1/3 the G3PF
depth is recommended.)
Countermeasure 2
Airflow
Vertical
direction
Base
G3PF
Duct or other
airflow-blocking object
If the depth direction of the
G3PF is obstructed by ducts,
the heat radiation will be
adversely affected.
Use ducts that have a
shallow depth, to
provide a sufficient
ventilation area.
(6) Ventilation Outside the Control Panel
If the ducts cannot be made
lower, place the G3PF on a
metal base so that it is not
surrounded by the ducts.

Air inlet
G3PF
Note 1. If the air inlet or air outlet has a filter, clean the filter regularly to prevent
it from clogging to ensure an efficient flow of air.
2. Do not locate any objects around the air inlet or air outlet, otherwise the
objects may obstruct the proper ventilation of the control panel.
3. A heat exchanger, if used, should be located in front of the G3PF to
ensure the efficiency of the heat exchanger.
(7) G3PF Ambient Temperature
The rated current of the G3PF is measured at an ambient
temperature of 40°C.
(8) The G3PF uses a semiconductor to switch the load. This
causes the temperature inside the control panel to increase
due to heating resulting from the flow of electrical current
through the load. G3PF reliability can be increased by adding
a ventilation fan to the control panel to dispel this heat, thus
lowering the ambient temperature of the G3PF.
(Arrhenius's law suggests that life expectancy is doubled by
each 10°C reduction in ambient temperature.)
G3PF rated current (A)
25 A
35 A
Required number of fans per G3PF
0.4 0.54
Example: For 10 G3PF SSRs with load currents of 35 A,
0.54 × 10 = 5.40
Thus, 6 fans would be required.
Note 1. Size of fans: 92 mm2, Air volume: 0.7 m3/min, Ambient temperature
of control panel: 30°C
2. If there are other instruments that generate heat in the control panel
in addition to SSRs, more ventilation will be required.
3. Ambient temperature: The temperature that will allow the SSR to
cool by convection or other means.
