Notes:
(2) _{The rated discharge current is the total current equally divided between each line to ground.}
(3) _{Surge polarity should be reversed between consecutive surges (+,-,+,-)}
(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.
