G9EC-1
DC Power Relays (200-A Models)
DC Power Relays Capable of
Interrupting High-voltage, High-current
Loads
• A compact relay (98 x 44 x 86.7 mm (L x W x 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 Compliant

Characteristics were measured after applying vibration
at a frequency of 10 to 55 Hz (single amplitude of 0.75
mm) to the test piece (not energized) for 2 hours each
in 3 directions. The percentage rate of change is the
average value for all of the samples.
