The 6287 is designed for use with DHC switch modules that include a means for connection to neutral. This device may be wired on the LOAD side of a DHC switch module or on the LINE side of any fixture using an electronic ballast, a low-voltage ballast, or any noise-generating source that does not require more than 5A 120 VAC. The 6287 prevents interference generated by fixture components from interfering with DHC signals. Small size for easier mounting at receiver or load device.
