Better Lighting. Better Energy. Better World

My home was built in the late 1950’s. Is the 3000 relay a compatible replacement to my original relays? If so, will it fit within my existing box?

Yes. The newer model 3000 relay is a compatible replacement for systems installed in 1946‐1985. It will fully replace the following models:  1550‐A, 1550‐B, 2500‐B, and 4000.  The 3000 includes screw terminals for the high voltage wire connections, eliminating the need for wire nuts on the HV side. This addition caused the base of the relay to be ½” wider than the original. The larger base is not a problem for most systems. It will only pose a problem if your existing system has relays that are double‐stacked or if the relays are mounted behind pilot transformers. The extra ½” will not allow the 3000 to be mounted behind another relay or transformer; it must be in the front most position. If the relay you need to replace is in the back row, simply change positions with other existing component, so the new 3000 can be on the front and the larger base accommodated for.
