Top 10 Residual Current Sensor Suppliers in China

Introduction to Residual Current Sensor

A residual current sensor, also known as a ground - fault current sensor, is a crucial device in electrical systems. It is designed to detect the imbalance between the live and neutral currents in an electrical circuit. In a healthy electrical system, the currents flowing through the live and neutral conductors should be equal in magnitude but opposite in direction. However, when there is a fault, such as a leakage current to the ground, the residual current (the difference between the live and neutral currents) will occur.

Residual current sensors play a vital role in electrical safety. They are widely used in various applications, including industrial electrical systems, residential electrical installations, and electrical equipment. By detecting the residual current, these sensors can trigger protective devices such as residual current circuit breakers (RCCBs) to cut off the power supply, preventing electrical shocks, fires, and other potential hazards caused by electrical leakage.
