TeSys LR9F electronic overload relay, thermal setting range 132-220A, class 20, for protection of motors 90-110kW@400V. to be mounted directly below a TeSys F 3-pole contactor LC1 F185, F225, F265, use of a support mounting plate LA7F901 is recommended (to be ordered separately). Motor protection includes thermal overload of 1-phase and 3-phase motors, phase failure, phase unbalance, prolonged starting times, stalled rotor conditions. On the front of the relay, it provides a thermal adjustement dial, buttons for test, stop & reset, a trip indicator, trip auxiliary contacts 1NO+1NC. Multi standards certified (IEC, UL, CSA, CCC, Marine), Green Premium compliant (RoHs/Reach).
