Load-Life Curves
Bulletin 500 Line contactors and starters are designed to provide
superior performance in a variety of applications. These load-life
curves are based on Rockwell Automation tests according to the
requirements defined in IEC 947-4. Actual contact life may vary
based on the application, duty cycle, and environmental conditions
from that indicated by the curves.
To find the contactor’s estimated electrical life, follow these
guidelines:
Contact Life for Mixed Utilization Categories AC3 and AC4
In many applications, the utilization category cannot be defined as
either purely AC3 or AC4. In those applications, the electrical life of
the contactor can be estimated from the following equation:
Choose the appropriate graph that most closely approximates the
utilization category of the application.
Locate the intersection of the life-load curve of the appropriate
contactor with the application’s operational current (I
e
) found on
the horizontal axis.
Read the estimated contact life in millions of operations along the
vertical axis.
