## Questions & Answers

**Q: Require 32 amps. Will a single three pole contactor with neutral suffice? Is there any circuit diagram available?**
A: We have another model PEF-319 for 30A listed in amazon. You need 3 x 32A single pole contactors if you wish to use PEF-301 for a load of 32A.

**Q: Please explain the workingof the device**
A: This device is used to automatically shift/switch supply voltage from a three phase connection, it senses the most healthy voltage amongst three phases and switches the supply to load by itself

**Q: in case of short circuit or  if  a person touched accidentally it will be shut down automatically**
A: This device takes decision in terms of Voltage presence and its quality in the 3 incoming phases. For short circuit protection or earth leakage you need to use MCB and RCCB.

**Q: What will the output if all the 3 phases are healthy?**
A: In such case i it can be programmed either to return on a pe designated pahase or it can remain in the last known healthy phase
