G9ED-1-B-AQ DC Power Relay (150A type) Capable of Interrupting High- voltage, High-current Loads A compact relay (L73 x W36x H67.2mm) capable of switching DC400V, 150A. (Max. 300A can be ap- plied) 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 am- bient atmosphere. Downsizing of parts and optimum design allow no restrictions on the mounting direction.
