Product Data Sheet
TeSys LRK thermal overload relay, thermal setting range 0.54-0.8A, tripping class 10A, for protection of 3-phase motors. Non differential device, it can be used with unbalanced loads. It provides a thermal adjustement dial, a manual-automatic reset selector, a test selector for simulation of a tripping, reset and stop buttons, 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 TeSys K contactors. Mounting on DIN rail or screw fixing, separated from the contactor, with using terminal block LA7K0064 (to be ordered separately).
