Note 1. When ordering, add the rated coil voltage to the model number.
Example: G5NB-1A DC5
Rated coil voltage
However, the notation of the coil voltage on the product case as well as on the packing will be marked as @@VDC.
Note 2. When ordering tape packing, add-S to the model number.
Be sure since-S is not part of the relay model number, it is not marked on the relay case.
