Information summarized below in reference to attached simplified wiring diagram for 110V dc power supply:
| Type of auxiliary device | Power consumption (W) @ 110Vdc | Mode of supply/average duration | Re-occurrence |
| Shunt closing release | 50W | short time/50ms | each closing cycle (according to application) |
| Shunt opening release | 50W | short time/70ms | each opening cycle (according to application) |
| Under voltage release |
| Continuous (10W) | Continuous |
| Electrical motor with gearing | 380W | short time/15s | each closing cycle (re-arming of the closing spring), according to switching cycles/application |
