DC Power Relays (60-A, 100-A Models) G9EA-1 DC Power Relays Capable of Interrupting High-voltage, High-current Loads A compact relay (73 x 36 x 67.2 mm (L x W x H)) capable of switching 400-V 60-A DC loads. (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. Downsizing and optimum design allow no restrictions on the mounting direction. Terminal Cover and DIN Track Adapters are also available for in- dustrial applications. UL/CSA standard UL508 approved. Note: Refer to Precautions on page 22.
