Ordering Information

List of Models

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.
