G9EH-1 DC Power Relay (300A type) Capable of Interrupting Highvoltage, High-current Loads • A compact relay (L111 x W60x H76.7mm) capable of switching DC400V, 300A. (Capable of interrupting max. DC300V, 2500A) • The switching section and driving section are gas-injected and hermetically sealed, allowing these compact relays to interrupt high-current. The sealed construction also achieves no arc space, space saving, and helps to ensure safe applications. In addition, the contacts have a high contact reliability that is unaffected by ambient atmosphere. • Downsizing of parts and optimum design allow no restrictions on the mounting direction. ■ Type standard G9EH-@-@-@-@ ➀ ➁ ➂ ➃ ➀ ➁ ➂ ➃ Classification Symbol Number of contact poles 1 Symbol Meaning of the symbol 1 pole Contact structure Blank Coil terminal form Blank 1a contact Connector terminal Automotive use Blank Available for automotive use ■ Classification Terminal form Classification Switching / current conduction type Coil terminals Contact terminals Connector terminal Screw terminals Contact structure Rated coil voltage 1a DC12V DC24V Type name G9EH-1 Note: Come with two M8 nuts for main terminals (contacts). ■ Ratings DC Power Relay ● Operation coil Rated voltage (V) Rated current (mA) Coil resistance () DC 12 583 20.6 DC 24 292 82.3 Operating voltage (V) Release voltage (V) Maximum voltage (V) Power consumption (W) 75% or less of rated voltage 8% or more of rated voltage 130% of rated voltage (at 23C within 10min.)
