Omron A5 Catalogue 2006 1-294 14/10/05 9:39 am Page 162 TDC Power Relay G9EC-1ext DC Power Relays Capable of Interrupting High-voltage, High- current Loads A compact relay (98 x 44 x 86.7 mm (L x W x H)) capable of switching 400V, 200 A DC loads. (Capable of interrupting 1,000 A at 400 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. Downsizing and optimum design allow no restrictions on the mounting direction. Terminal Cover is also available for industrial applications. UL/CSA approval pending. Model Number Structure Model Number Legend 1. Number of Poles 3.
