Module minimizes earth leakage currents
The LeaXield module couples a current phase-shifted by 180° from the leakage current to the phases and thus conducts system-related leakage currents back to the source, thus avoiding unintentional tripping of the residual current circuit breakers and increasing system availability.
LeaXield is available for load currents of up to 50 A at a rated frequency of 50/60 Hz and phase to phase voltages of up to 530 V AC and is connected between the residual current switch and the EMC input filter of the inverter in standard industrial three-phase TN networks. The module can be used up to a leakage current of 1 A, and leakage current compensation covers a wide frequency range from 150 Hz to about 30 kHz.
Due to its compact design, LeaXield is also suitable for retrofitting existing systems. The installation effort is low as no external power supply is required.
