G9EH-1 DC Power Relay (300A type)

Automotive DC Power Relays: G9EH-1 for Automotive
  • New

Capable of Interrupting Highvoltage,
High-current Loads

  • A compact relay (L111 x W60 x H76.7 mm) capable of switching DC400 V, 300 A. (Capable of interrupting max. DC300 V, 2500 A)
  • 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.
