DC Power Relay (60 A and 100 A Type) G9EA-1

DC Power Relay (60 A and 100 A Type) G9EA-1

· DC power relay that can cut off high voltage, high current direct current loads.
· Small size with height 67.2 mm × width 36 mm × length 73 mm, DC400V, 60A switching capable (maximum DC300V, 600A cutoff capable).
· Due to the switching and driving parts' gas filling and sealing structures, the small size makes it capable of cutting off high capacity loads, and achieves arc space free space saving and stability.
· At the same time, it features highly reliable contact free from environmental effects.
· No limitations to mounting direction due to parts miniaturization and appropriate matching design.
· Terminal cover for general industrial use with DIN rail adapter also available.
· UL/CSA standard UL508 acquired.

DC Power Relay Specifications

G9EA-1 external appearance

G9EA-1 external appearance

  • A compact relay (67.2 × 36 × 73 mm [H × W × L]) capable of 400-V DC 60-A switching. (Capable of interrupting 600 A at 300 V DC max.)
  • The switching section and driving section are gas-injected and hermetically sealed, allowing these compact relays to interrupt high-capacity loads. Also requires no arc space, saves space, and helps ensure safe applications. Also provides high contact reliability with contacts that are not affected by the surrounding atmosphere.
