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.
