Replacement Parts
G32A-A Power Device Cartridge
The G32A-A Power Device Cartridge (a Triac Unit) can be replaced with a new one. When the temperature indicator has changed from pink to red,
the triac circuitry may have malfunctioned possibly by an excessive flow of current, in which case, dismount the damaged cartridge for replacement.
The damaged cartridge can be replaced with a new one without disconnecting the wires from the G3PA.
Improve the heat radiation efficiency of the G3PA before replacing the cartridge.
The G32A-A Power Device Cartridge can withstand an excessive current for a short period of time, such as may be caused accidentally by the
short circuitry of the load, in which case the temperature indicator will not turn red.
Be sure to turn OFF the power supply when replacing the Cartridge. Supplying power with the Cartridge removed may result in malfunction.
To remove or replace the Power Device Cartridge for the G3PA-210B-VD, G3PA-220B-VD, or G3PA-420B-VD(-2), use the special tool provided
with it for extraction. (No special tool is required for other models.)
The G3PA can be broadly divided into two series: Previous models and models with model numbers that end with "-VD." The Cartridge shown at
the right cannot be mounted to models in the G3PA-
@@@
B-(-US) Series.
