2 DC contactors and circuit-breakers, however, are disadvantaged by their noise and bulk. OMRON has improved on the standard DC circuit that switches using a contactor or circuit-breaker by developing the G9EA/G9EB/G9EC DC Power Relay Series. These Relays enable switching high - voltage and high -capacity loads. The switch's gas-filled construction allows a considerable reduction in the relay switch size, while also lowering the operating noise during load switching. Furthermore, the new design has decreased the Power consumption of the coil and achieved long-term contact with the same class (load switching) of G9EA DC Power Switching TechnologiesSpace-savingNo arc space neededPower-saving30% less Power consumptionCompact70% less volumeQuiet50% lower operating noiseSafe,reliable design*Smaller and quieter for a variety of DC applicationsAutomobilesHybrid cars, fuel-cell cars, compact electric passenger vehicles, VehiclesBattery-operated golf carts, forklifts, AGV (automated guided vehicles)

(Capable of interrupting 600 A at 300 VDC max.) The switching section and driving section are gas-injected and hermetically sealed, allowing these compact Relays to interrupt high -capacity loads. The sealed construction also requires no arc space, saves space, and helps ensure safe applications.
