DC Power Relay
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.

■Classification
Note:1. Come with two M6 screws for main terminals(contacts).
2. Come with two M3.5 screws for screw-type coil terminal products.
3. If you are interested in a connector joint for F-coil terminal, please contact our sales representatives.
■Ratings
●Operation coil
Note:1. Values of the rated current and the coil resistance are at coil temperature of +23C, and have a tolerance of ±10%.
2. The figures for the operating characteristics are at a coil temperature of 23C.
3. Value of the maximum voltage is the maximum voltage that can be applied to the relay coil.
