Querschnittsrechner is a free mobile application developed by Dominik Vincenz for Android users. It is a tool for calculating minimum conductor cross-sections required for three-phase and single-phase alternating current (AC) systems. With this app, you can enter the required power or current, configure the maximum voltage drop and cable length, and the app will calculate the minimum conductor cross-section required for the system.

This app is designed for professionals who work with electrical systems and require quick and easy calculations for minimum conductor cross-sections. It is important to note that the app is not liable for any damage resulting from incorrect usage or calculation errors. Querschnittsrechner is a useful tool for electrical engineers, electricians, and other professionals in the field of electrical engineering.
