Abstract
Overview
IEC 60077-4:2003 is an international standard developed by the International Electrotechnical Commission (IEC) specifically for railway applications. It details the rules and requirements for AC circuit-breakers used in electric equipment for rolling stock. These circuit-breakers are designed to connect with AC overhead contact lines, operating at nominal voltages consistent with . The standard complements the general requirements covered in , focusing on electrotechnical components vital for safe and efficient railway operation.
