G9EA-1
DC Power Relays (60-A, 100-A Models)
DC Power Relays Capable of Interrupting
High-voltage, High-current Loads
• A compact relay (73 x 36 x 67.2 mm (L x W x H)) capable of switching 400-V
60-A DC loads. (Capable of interrupting 600 A at 300 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 and DIN Track Adapters are also available for industrial
applications.
• UL/CSA standard UL508 approved.
■Model Number Legend
■List of Models
Note 1. Two M5 screws are provided for the contact terminal connection.
Note 2. Two M3.5 screws are provided for the coil terminal connection.
■Ratings
●Coil
Note 1. The figures for the rated current and coil resistance are for a coil temperature of 23°C and have a tolerance of ±10%.
Note 2. The figures for the operating characteristics are for a coil temperature of 23°C.
Note 3. The figure for the maximum voltage is the maximum voltage that can be applied to the relay coil.
●Contacts
RoHS Compliant
