Notes:
(2)
The rated discharge current is the total current equally divided between each line to ground.
Surge polarity should be reversed between consecutive surges (+,-,+,-)
(3)
(4)
Applies only to GDT with optional Fail-Short. GDT operates and will survive with Fail-Short activation.
•
•
At delivery AQL 0.65 Level II, DIN ISO 2859.
Models with the optional Fail-Short assembly activate at low temperature (215 °C – 217 °C) when required. These models are designed to be soldered either
manually or using a selective soldering process that does not exceed 210 °C, below the temperature that the Fail-Short assembly would activate.
