2 FRANKE s GMKP GMC Capacitor Contactor General Information CAPACITOR CONTRACT of GMKPGMC can be use din V,AC,50-60Hz up to control 60Kvar capacitor, when a capacitance is switched to an AC system. The result is a resonant circuit damped to a greater or lesser degree. In addition to the nominal current, the capacitor accepts a transient current that is a multiple of (as many as200 times) its nominal current. Fast switching, low-bounce contactors should be used. Because of the leading contacts, the inrush current spikes (reverse charging operations) are limited or damped by resistance wires. These current spikes would lead to welding of the contactor s main contacts and they are also harmful for the capacitors. Reduction of the inrush currents also avoids transients and voltage sags. Leading contacts with a wiper function are used in these capacitor contactors, is each leading contact is linked to the contactor yoke by a permanent magnet. The leading contacts close before the main contacts and open when the main contacts are with certainty closed. This feature of the capacitor contactors guarantees effective, stable operation throughout useful life. The single controlled leading contacts also enhance resistance to soiling during operation. The capacitor contactors are suitable for direct switching of low-inductance and low-loss capacitor banks (IEC 831,VDE 0560)with or without detuning reactors. They feature leading auxiliary switches and damping resistors to reduce peak inrush to<70* Iin (inrush current). The capacitor contactors are weld inrush current of 200* Iin. The backup fuses gl (gg) should be scaled for 1.6 to 1.8* Iin all capacitor contactors come with an auxiliary contact (normally open). Features Excellent damping of inrush current Improved power quality(e.g. Avoidance of voltage sags) Longer useful life of main contacts of capacitor contactor Soft switching of capacitor and thus better useful life Enhanced mean lifetime of PFC system Reduced ohmic losses Leading contacts with wiper function High quality and long operation life
