What is Inductive Load Switching and Protection about?

This document provides calculation examples for selecting varistors to limit switching transients and ensure EMC compliance. It examines switching off an inductive load and protecting equipment connected to a 230V mains. For the inductive load, it calculates transient voltage, current, energy absorption and dissipation to select a varistor rated for the application. For EMC compliance, it determines the surge current from a 4kV test generator and selects a varistor that can withstand the current over 10 rep
