Solid State Relays Zero Switching TypeRMD Hybrid Relay • Hybrid Relay: SSR + EMR combination • Current rating @ 60˚C: 30 AAC, 40 AAC • Nominal voltage ratings: 240 VAC, 227 VAC/ 480 VAC + Neutral • Control voltage: 24 VAC, 120 VAC, 240 VAC • Mercury-free, leading to a safer environment • Similar mounting to mercury relays • RoHS compliant • Switching with arc-free operation • Switching rate: up to 20 cycles per minute • Operating life: 4 million operating cycles 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 Selection Guide 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).
