Series FMAC ECO and FMBC ECO are produced without potting compound, making them less costly and lighter weight than conventional filters. ECO Series filters are built to be used with 480 Vac installations and are available in single or 2-stage versions. FMAC ECO single stage filter is available from 16 to 150A. FMBC ECO 2-stage filter possesses broader attenuation band with leakage current of just 5 mA, making it ideal for use in installations equipped with residual current circuit breakers.
