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
