G9EA-1 DC Power Relays (60-A, 100-A Models) 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 industrial applications. • UL/CSA standard UL508 approved. RoHS Compliant Refer to "DC Power Relays Common Precautions". ■Model Number Legend 1. Number of Poles 3.
