LR9F7375

LR9F7375 is a TeSys LR9F electronic overload relay. It features a thermal setting range of 200-330A, class 10, for the protection of motors 132-160kW at 400V. It is to be mounted directly below a TeSys F 3-pole contactor LC1 F225, F265, F330, F400, F500, use of a support mounting plate LA7F902 is mandatory (to be ordered separately). Motor protection includes a thermal overload of 1-phase and 3-phase motors, phase failure, phase unbalance, prolonged starting times, and stalled rotor conditions. On the front of the relay, it provides a thermal adjustment dial, buttons for test, stop & reset, a trip indicator, and trip auxiliary contacts 1NO+1NC. It complies with VDE 0660, IEC 60947-4-1, EN 60947-4-1, IEC 60255-17, IEC 60255-8 standards. It is certified by UL, CSA, and UKCA. It has IP20 conforming to IEC 60529 IP20 conforming to VDE 0106 degree of protection. It is used in motor protection application.
