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 Refer to "DC Power Relays Common Precautions". ■Model Number Legend G 9 M C -@ -@ - @- @ — — — — 2 3 1: 1 pole 4 2. Contact Form Blank: SPST-NO - 1 1. Number of Poles G 9 E C 1 3.
