GMC series AC Contactors (Magnetic Contactor) provide remote control of primarily electric motors and compensation & heating systems by cable. They protect the instruments and equipments against overload currents by using thermal relays, for capacitor switching contactor. While switching on a capacitive circuit, a high frequency and large transient current peaks are produced. Switching of capacitor for a single or one of the capacitor banks are different from each other. Step by step "switching on" operation is more difficult for contactor than capacitor bank. Because during this operation for capacitor bank, compensated current occurs. For this reason selecting of suitable contactors the compensating current must be take into consideration for 50kVAR and above, and for less than 50kVAR can be omitted.
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)
