RTI thermal electrical relay is designed for protecting electric motors from overload, phase unbalance, overcrank condition and rotor jamming. It is installed directly onto KTI and KMI AC contactors. To ensure shortcircuit protection, the unit should be supplied with fuses and modular circuit breakers intended for the correspondent value of rated actuating current. Correspond to the requirements EN 60947-1, EN 60947-4-1, EN 60947-5-1. High accuracy of operation. Convenient adjustment. Wide range.
