Product Description Ordering Key
RMD 3 H 48 HA 40
RMD3H combines the benefits of solid state relays and electro- mechanical relays to provide a hybridrelay. This meansthat there is virtually no contact arc- ing and much less heat emis- sion inside the panel. RMD3H switches heaters on three legs while RMD2H has two poles whichareswitched andthe

thirdone is directlyconneced between the L2 and the T2 ter- minals.
This hybrid relay also provides a solution which does not contain mercury and is RoHS compli- ant. The maximum current reached per pole is 40AAC in a surrounding temperature of
60˚C (140˚F).
