Performance Curves
RUMC21BD
Electrical Durability of Contacts
Durability (inductive load) = durability (resistive load) x reduction coefficient.
Resistive AC load
X Switching capacity (kVA)
Y Durability (Number of operating cycles)
Reduction coefficient for inductive AC load (depending on power factor cos ϕ)
Y Reduction coefficient (A)
Maximum switching capacity on resistive DC load
X Voltage DC
Y Current DC
Note : These are typical curves, actual durability depends on load, environment, duty cycle, etc.
