KAR01 and KAR11 are protection devices designed to ensure safety by detecting leakage currents in electrical systems.

Operating in conjunction with toroidal current transformers, they measure fault currents and trigger the circuit breaker.

While KAR01 provides standard protection, the KAR11 model features a harmonic filter, ensuring reliable performance in environments with high electrical noise.

Important Usage Notes

Full Compatibility: For the most efficient results, Grup Arge Toroidal Current Transformers must be used with Grup Arge KAR series relays.

KAR11 Advantage: If your installation includes many devices that generate harmonic noise, such as motor drives, UPS units, or LED lighting, the KAR11 model with a harmonic filter should be preferred to prevent nuisance tripping.
