Note: 1. Other than the above models, minute load models switching 0.1 A are available. When ordering a minute load
model, add the suffix A to the model number (i.e., VB-2211A for example).
2. SC connectors can be connected to VB models.
3. Models with ground terminals are also available. When ordering a ground terminal model, add the suffix E to the
model number (i.e., VB-2211E for example).
* Since the actuator is incorporated into the monoblock switch, the actuator cannot be replaced.
