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.
