Ground Terminal VB-5121 --- None: Without ground terminal VB-6121 --- E: With ground terminal 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.
