G9EC124DC Omron

DC Power Relays (200-A Models) G9EC-1 DC Power Relays Capable of Interrupting High- voltage, High-current Loads A compact relay capable of switching 400-V 200-A DC loads. (Ca- pable of interrupting 1,000 A at 400 VDC max.) The switching section and driving section are gas-injected and her- metically 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. Downsizing and optimum design allow no restrictions on the mounting direction. Terminal Cover is also available for industrial applications. UL/CSA standard UL508 approved. Model Number Structure Model Number Legend G9EC-@-@-@-@ 12 3 4 1. Number of Poles 1: 1 pole 2.
