The thermal relay e.pro.ukh.3.93.3-4 is designed to protect three-phase asynchronous electric motors with a short-circuited rotor from overload, load asymmetry and phase failure. The relay has a range of operating current adjustment 80–93 A and is designed for installation directly on contactors of the e.pro.ukc series - size 3 and 4. The device is three-pole and has additional contacts 1NO+1NC for signaling and control in command circuits. It is suitable for applications in industrial panels and electric drive systems, where reliable protection of three-phase electric motors is required.
