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]
・ Compact size with height 86.7 mm × width 44 mm × length 98 mm, compatible with 400 V DC, 200 A opening and closing (Maximum 400 V DC, 1,000 A can be cut off)
・ The gas filling and sealing structure of the opening/closing part and drive part enables high-capacity load cutoff due to its small size. In addition, arc space-free space saving and safety are realized. At the same time, it achieves high contact reliability of contacts that are not affected by the surrounding atmosphere
・ No restrictions on mounting direction due to miniaturization of parts and proper matching design
・ Assortment of terminal covers required for general industrial machinery
・ UL/CSA standard UL508 acquisition
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.
