RTI series electrothermal relay is an electrical switching device with its own power consumption. The RTI series electrothermal relay is designed to protect electric motors from overload, phase asymmetry, delayed start, and rotor stalling. It is installed directly on KTI and KMI series contactors. To protect against short circuits, fuses or circuit breakers with a corresponding rated tripping current must be provided.
Complies with GOST R 50030.2 requirements.
