What is a capacitor contactor with a damping resistor?
Capacitor contactors with damping resistors make use of pre-switching auxiliary contacts. They close before the main contacts and pre-load the capacitor thus avoiding current peak values. This positively influences the life expectancy of the capacitor and the positive impact on the power quality. The values above reflect typical specifications.
What is the main function of a capacitor contactor?
The main function of the capacitor contactor lies in the auxiliary contact, which is very different from the conventional contact. The 33 and 34 contacts on the auxiliary contacts of the capacitor contactor have the same function as the conventional auxiliary contacts, which act together with the main contacts of the contactor.
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
