NOTE: For DC input, A1 have to be +, otherwise it would short circuit from protection module
Performance CurvesElectrical Durability of Contacts
Durability (inductive load) = durability (resistive load) x reduction coefficient.
Resistive AC loadXSwitching capacity (kVA)YDurability (Number of operating cycles)
Reduction coefficient for inductive AC load (depending on power factor cos ϕ)YReduction coefficient (A)
Maximum switching capacity on resistive DC loadXVoltage DCYCurrent DC
Note : These are typical curves, actual durability depends on load, environment, duty cycle, etc.
