There really is no minimum line current requirement for the Versa-Tech reclosers. All protection functions to operate the recloser as programmed on any of the Versa-Tech models is accomplished via the fault current. In other words, the recloser can sit at 0A or 2A load and experience a fault and then power up, operate 4 times, and lockout. 

• The Versa-Tech is a line powered device, meaning that it is a live and energized
• The control and the mechanism, or switch, are at the same potential as the system
• A current transformer inside of the Versa-Tech reclosers is used to harvest line currents and fault currents to power the electronics within the Versa-Tech and charge the capacitors that are used actuate the vacuum bottle
• Once a fault is indicated by the device, it relies minimum trip setting and TCC curve to operate. The minimum trip is programmable from 30A to 800A . 

There is a line current requirement for added features to function on the Versa-Tech, such as the radio. The radio is also referred to as a peripheral of the recloser and it requires additional power to be able to operate.  

For the radio:

• Includes WiFi, Digi (900MHz), and legacy SiFLEX (900MHz) radios
• There is a 10A load threshold on Versa-Tech LT, Versa-Tech I, and Versa-Tech II
• There is a 6A load threshold on Versa-Tech XC. There is a 10A load threshold for the SCADA cellular modem, which is only available on the Versa-Tech XC
• A current transformer inside of the Versa-Tech reclosers is used to harvest line currents to power the radio
