Technical data

SIRIUS 3R
The characteristic curves show the contact endurance of the contactors when used to switch resistive and inductive three-phase loads (AC-1/AC-3), de-pending on the breaking current and the rated operational volt-age. It is assumed that the oper-ating mechanisms are switched randomly, i.e. not synchronized with the phase angle of the sup-ply system.
The rated operational current Ie for the AC-4 utilization category (breaking six times the rated op-erational current) is designed for a contact endurance of at least 200 000 operating cycles.
If a shorter endurance is suffi-cient, the rated operational cur-rent Ie/AC-4 can be increased.
For mixed operation, i.e. nor-mal switching (breaking the rated operational current ac-cording to the AC-3 utilization category) in combination with in-termittent inching (breaking sev-eral times the rated operational current according to the AC-4 utilization category), the contact endurance can be calculated approximately from the following equation:
Where:X Contact endurance for mixed
operation in operating cyclesA Contact endurance for normal
operation (Ia = Ie) in operating cycles
B Contact endurance for inching (Ia = multiple of Ie) in operating cycles
C Inching operations as a percentage of total switching operations
Endurance of the main contacts
