3 3RT, 3TB, 3TF Contactors for Switching Motors 3RT10 contactors, 3-pole, 3 ... 250 kW Endurance of the main contacts The characteristic curves show the contact endurance of the contactors when switching resistive and inductive AC loads (AC-1/AC-3) depending on the breaking current and rated operational voltage. It is assumed that the operating mechanisms are switched randomly, i. e. not synchronized with the phase angle of the supply system. The rated operational current I e complies with utilization category AC-4 (breaking six times the rated operational current) and is intended for a contact endurance of at least 200 000 operating cycles. If a shorter endurance is sufficient, the rated operational current Ie /AC-4 can be increased. If the contacts are used for mixed operation, i. e. normal switching (breaking the rated operational current according to utilization category AC-3) in combination with intermittent inching (breaking several times the rated operational current according to utilization category AC-4), the contact endurance can be calculated approximately from the following equation: A X C 1 --------- 100 A = ------------------------------------------------------- + ⎛--- – 1⎞ ⎝B⎠ Characters in the equation: X Contact endurance for mixed operation in operating cycles A Contact endurance for normal operation (I a = I e ) in operating cycles B Contact endurance for inching (I a = multiple of I e) in operating cycles C Inching operations as a percentage of total switching operations Diagram legend: PN = Rated power for squirrel-cage motors at 400 V Ia = Breaking current Ie= Rated operational current 3/18 Siemens LV 1 T · 2009 © Siemens AG 2009 Size S00 ! 8 & $ " & $ " & $ " F A H= JE C ?
