(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.
