Relationship between the G3PE and Ducts or Other
Objects Blocking Airflow
If the depth direction of
the G3PE is obstructed by
ducts, the heat radiation
will be adversely affected.
Ventilation Outside the Control Panel
Note: 1. If the air inlet or air outlet has a filter, clean the filter regularly
G3PE Ambient Temperature
15A and 25A models have ambient temperature of 40°C, while 35A
and 45A models have 25°C ambient Temperature. The G3PE 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. The G3PE reliability can be
increased by adding a ventilation fan to the control panel to dispel
this heat, thus lowering the ambient temperature of the G3PE.
(Arrhenius's law suggests that life expectancy is doubled by each
10°C reduction in ambient temperature.)
