TeSys LRF – electronic thermal overload relay – 380…630 A – class 10/20

TeSys LR9F electronic overload relay, thermal setting range 380-630A, selectable class 10-10A-20, for protection of motors 250-355kW@400V. to be mounted directly below a TeSys F 3-pole contactor LC1 F400, F500, F630, F800, use of a support mounting plate LA7F902 is mandatory (to be ordered separately). The motor protection includes thermal overload of 1-phase and 3-phase motors, phase failure, phase unbalance, prolonged starting times, stalled rotor conditions, completed with an overheating alarm function. On the front, the relay provides a thermal adjustement dial, buttons for test, stop & reset, a trip indicator, trip auxiliary contacts 1NO+1NC, and alarm circuit terminals. Multi standards certified (IEC, UL, CSA, CCC, Marine), Green Premium compliant (RoHs/Reach).
