External-Mount Heat Sink for 40A SSR (Rectangular)

This is a long and low profile heatsink made from anodized aluminum alloy. This external mount heat sink is for dissipating the heat from 25A or 40A single phase SSR. The SSR and its wiring will stay inside the box. The advantage of using a external mounting is that there is no need for venting hole or cooling fan in the controller box.  Mounting screws and heat conductive grease are included.

User will need to cut a 70 x 55 mm (2.75" x 2.2") rectangular hole for the SSR.
