RMD3H combines the benefits of solid state relays and electromechanical relays to provide a hybrid contactor. 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 contactor also provides a solution which does not contain mercury and is RoHS compliant.
The maximum current reached per pole is 40 AAC in a surrounding temperature of 60°C (140°F).
