7 microamps (µA)

The 2RS rubber seals offer better protection against liquid and fine particulates than metal shields (ZZ)

which facilitates rapid field replacement using the PIRR replacement relay module without requiring a full rewire

Adjustments to the dial only modify the cut-out (off) temperature

Corrosion Resistance: Internal pin and port materials are selected to resist erosion and common system contaminants
