3 Phase Hybrid Relay - RMD Series - CARLO GAVAZZI Automation Components
Buffalo Grove, IL, USA
3 Phase Hybrid Relay
RMD Series
3 Phase Hybrid Relay RMD Series
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 connected 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). 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

Single Phase Hybrid Relay RMD Series
The RMD houses semiconductor triacs and mechanical contacts that compliment each other. On applying the control voltage, triacs are activated. After a short delay, an electromechanical relay is activated. This switching method protects the contacts of the electromechanical relay and reduces heating of the triacs. The same principle applies during removal of the control input. The result is millions of trouble-free cycles in a compact and modular switching package. Hybrid relay: Solid State Relay / Electromechanical Relay Operational ratings up to 230V, 20A ACrms Integral bypassing of semiconductors Internal over-temperature protection Compact 17.5mm wide housing Standard modular design DIN rail mounting No need for external heatsink Minimum audible noise Fit and forget: millions of switching cycles Ideal for switching of resistive single phase loads in residential buildings
