Toroidal Leakage Current Relays

General Features

Leakage current relays are safety devices that automatically switch off the circuit by detecting leakage currents that may occur in electrical systems. It has a wide range of uses from homes to industrial facilities and plays a critical role in terms of electrical safety.

KAR01 and KAR11 protect the system from overload and short circuit currents in case leakage current is detected. The leakage current protection relay is used together with the toroidal current transformer, and it measures the leakage current value coming from the toroidal transformer and ensures that the circuit breaker is activated.

In addition, the KAR11 model has a harmonic filter and is not affected by harmonic signals occurring on the line. In this way, it can be used easily in environments with harmonic noise.
