10 C5 - Contact Life C5 Determining Contact Life To determine the contactor s estimated electrical life, follow these guidelines: 1. Identify the appropriate Utilization Category from Table. 2. On the following pages, choose the graph for the Utilization Category selected. Table IEC Special Utilization Categories (Number of operations under load) ➊ 3. Locate the Rated Operational Current (l e ) along the bottom of the chart and follow the graph lines up to the intersection of the appropriate contactor s life-load curve. 4. Read the estimated contact life along the vertical axis.
