6 FAQs about [Contactor capacitor only]
What is a capacitor contactor?
The contactors for capacitor switching is actually composed of a conventional contactor as well as extra auxiliary contacts and wires (resistance wires). The main function of the capacitor contactor lies in the auxiliary contact, which is very different from the conventional contact.
Which contactors are suited for capacitor bank switching?
Application The A...and AF...contactors are suited for capacitor bank switching for the peak current and power values in the table below. The capacitors must be discharged (maximum residual voltage at terminals < 50 V)before being re-energized when the contactors are making.
What type of contactors can be used on multi-step capacitor bank?
The use of standard A 9 A 110 3-pole contactors is then possible on multi-step capacitor bank. The capacitors must be discharged (maximum residual voltage at terminals < 50 V)before being re-energized when the contactors are making. In these conditions, electrical durability of contactors is larger than 100 000 operating cycles. Selection Table
How many contactor versions does ABB offer?
ABB offers 3 contactor versions according to the value of the inrush current peak and the power of the capacitor bank. UA..RA Contactors for Capacitor Switching(UA 16..RA to UA 110..RA) with insertion of damping resistors. The insertion of damping resistors protects the contactor and the capacitor from the highest inrush currents. UA...
What is the maximum thermal current a capacitor can withstand?
Standard IEC 60831-1 Edition 2002 specifies that the capacitor must therefore have a maximum thermal current I Tof: I T= 1.3 x 1.15 x I n= 1.5 x I n Consequences for the Contactors To avoid malfunctions (welding of main poles, abnormal temperature rise, etc.), contactors for capacitor bank switching must be sized to withstand:
How does a CEM_CN capacitor work?
Capacitors are pre-charged through resistors that reduce the peak current to the contactor when CEM_CN special contactors are switched on. After the pre-charge, the main contactors close allowing passage of rated current.
