ECM-RACEWY3, designed to house up to three ETA electrical control modules to provide up to three separate 20A AC legs for up to 60A of power distribution. If three sequenced sections are not needed, two ECM-3BP blank plates are included to cover unused ECM module slots. Other blank plates are available as an accessory item (ECM-3BP). ECM-RACEWY3 can be mounted into most racks that have at least 30-inch internal height and raceway has breakaway mounting tabs that make it convenient to secure raceway in most applications.
