Called the G9EC-X1, “the switching and conducting sections are gas-filled and hermetically sealed, allowing these relays to interrupt high-power loads. The airtight design also requires no arc space,” according to the company.
With dimensions of 98 x 44 x 86.7 mm, it identical in size to the model.
The contact resistance inside the relay is less than 0.5 ohms, Omron said (Electronics Weekly checks this figure, and it's probably 0.5mΩ). "As a result, the device can withstand a continuous transfer current of 200 A at 85°C."
