Primarily, understanding the selection codes of the capacitor switching contactors; to start with is the range name, HDC19s, which is followed by the numerical denoting the frame current varying from 25A to 175A. Next to the sequence, we have the list of auxiliary contacts based on the number of NO and NC contacts.
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.

Standard Contactors(A 12 to A 300 and AF 50 to AF 750) Maximum permissible peak current Î < 30 times the nominal rms current of the switched capacitor. Contactors for Capacitor Switching
FRAKO capacitor switching contactors are designed for long life, yet they are compact and have low power losses. When switched capacitors do not include series connected reactors, it is very important to use contactors with pre-charge resistors.
Use K3-..K contactors with pre-charge resistors for switching capacitors that do not have a series reactor (filter, tuning, detuning, etc.). The pre-charge resistors will reduce transients associated with typical capacitor switching and extend capacitor life. FRAKO Type K contactors are rated for a specific range of capacitive current (or kVAR).
CJ19 series contactor for capacitor switching (hereinsafter referred to as contactor) is mainly used in power systems with AC 50Hz/60Hz, rated operating voltage up to 690V and rated power up to 130kvar. It is used to connect and disconnect shunt capacitors with the aim to improve power factor.
