Schneider 50442 Toroid Current Sensor

Feature & Principle

It is a closed toroidal current sensor for residual current monitoring. It detects the vector sum of phase currents in the circuit, converts residual leakage current into weak secondary signal and transmits to Vigirex earth fault relay. It provides overvoltage and short-circuit protection for the relay, features high measurement accuracy, stable performance for long-term leakage monitoring of power distribution circuits.
