Auxiliary Contactor Delay On Make or DelayTimer for AC/DC contactor 1NO 1NC
UT series auxiliary contact blocks are installed on the top of UKC1 series AC contactor for expanding the couples of auxiliary contacts points.
IEC utilization categories
The current rating of the AC/DC contactor depends on utilization category. Example IEC categories in standard 60947 are described as:
AC-1 - Non-inductive or slightly inductive loads, resistance furnaces
AC-2 - Starting of slip-ring motors: starting, switching-off
AC-3 - Starting of squirrel-cage motors and switching-off only after the motor is up to speed. (Make Locked Rotor Amps (LRA), Break Full Load Amps (FLA))
AC-4 - Starting of squirrel-cage motors with inching and plugging duty. Rapid Start/Stop. (Make and Break LRA)
