This app is very helpfull and easy to use. Within minutes it is possible to set-up a complete motor control loop and test it. However I do miss some simple components, like standard fuses and PTC relay. The simulations works also very nice, but would like some improvements on check up of correct numbering. When having multiple contacts from one single relay the program should check if contact terminals are used double. It would also be a great feature if trip ratings and power consumption can be filled in and checked. Trip in case power consumption is higher than trip settings. Looking forward for the next update.
