Product Data Sheet
TeSys LR9D electronic overload relay, 8A/690V, thermal setting range 1.6-8A, selectable tripping class 5-10-20-30, for protection of 3-phase motors 0.75-3kW@400V. Differential device with phase failure and load unbalance detection. It provides a thermal adjustement dial, buttons for test, stop and reset as well as manual-automatic reset selector, dipswitches for tripping class selection, a flag indicator and 2 auxiliary contacts 1NO+1NC for fault signalling. Settings are protected by a transparent cover lockable by sealing. Connection by screw clamp terminals, it connects directly to the bottom terminals of 3-pole contactors LC1D09-D38. Mounting on DIN rail or screw fixing, separated from contactor, with use of the terminal block LAD7B205 (to be ordered separately). Multi-standards certified (IEC, UL, CSA, CCC), Green Premium compliant (RoHs/Reach).
