DC Power Relay (60 A and 100 A Type) G9EA-1
Caution
Product Description
DC power relay capable of interrupting high voltage high current DC loads.
[Features]
· The contacts are not affected by the ambient atmosphere and so ensure high contact reliability.
· No limitations to mounting direction due to parts miniaturization and appropriate matching design.
· Terminal cover and DIN track adapters are also available for general industrial applications.
· UL/CSA standard UL508 approved.
· [Applications]
· For interrupting high voltage, high current DC loads.
DC Power Relay Specifications
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.
