DC Power Relay (200A Type) G9EC-1

DC Power Relay (200A Type) G9EC-1
  • On Sale Till 31/03/2024
  • Volume Discount

A DC power relay that is designed with low noise, long lifespan, and environmental resistance to cut off DC loads with high voltage and high current.
[Features]
・ The compact size of height 86.7 mm × width 44 mm × length 98 mm supports 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
・ Achieves arc space-free space saving and safety
・ 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
[Applications]
・ Widely available for factory automation and non-factory automation devices
