G9EA-1 DC Power Relays (60-A, 100-A Models) 

G 9 E A 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 industrial applications. 

- UL/CSA standard UL508 approved.
