Information
TeSys LR9D electronic overload relay, 100A/1000V, thermal setting range 60-100A, tripping class 10, for protection of 3-phase motors 37-45kW@400V. Differential device with phase failure and load unbalance detection. It provides a thermal adjustement dial, buttons for test, stop and reset, a flag indicator and 2 auxiliary contacts 1NO+1NC for fault signalling. Settings are protected by a transparent cover lockable by sealing. Connection by bolt terminals for bars or cables with lugs, it connects directly to the bottom terminals of 3-pole contactors LC1D115, D150. Mounting on DIN rail or screw fixing, separated from contactor, can be done without accessories. Multi-standards certified (IEC, UL, CSA, CCC, Marine), Green Premium compliant (RoHs/Reach).
