G9EC-1 DC Power Relays(200-A Models)

DC Power Relays Capable of Interrupting High-voltage, High-current Loads

    A compact relay (98 × 44 × 86.7 mm (L × W × H)) capable of switching 400-V 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 standard UL508 approved.
RoHS適合
