For Utilization Category AC-1 and According to Required Electrical Durability
Maximum Operational Current (on-load factor
Increase in Operational Current by Paralleling of Poles
Apply the following multiplying factors to the current values given above; these factors take into account
the often unbalanced current distribution between poles:
• 2 poles in parallel: K = 1.6
• 3 poles in parallel: K = 2.25
• 4 poles in parallel: K = 2.8
Electrical durability (Ve
NOTE: For 660 V, multiply the number of operating cycles by 0.8.
Example
Ve = 220 V, Ie = 200 A, q = 40 °C (104 °F), Ic = Ie = 200 A. 600,000 operating cycles required.
The above selection curves show the contactor rating needed: CR1F400.
