## **Product Descri tion p** 

RMD3H combines the benefits of solid state relays and electromechanical relays to provide a hybrid relay. This means that there is virtually no contact arcing and much less heat emission inside the panel. RMD3H switches heaters on three legs while RMD2H has two poles which are switched and the 

third one is directly conneced between the L2 and the T2 terminals. 

This hybrid relay also provides a solution which does not contain mercury and is RoHS compliant. The maximum current reached per pole is 40AAC in a surrounding temperature of 60˚C (140˚F).

WARNING: Internal power supply in RMD2H and RMD3H24 is taken through terminals L1-L3, while for RMD3H48 it is taken through L1-N. If these are not connected correctly, the internal bypass relays will not work. The ‘N’ terminal must be left unconnected for RMD2H and RMD3H24.
