TeSys LRD thermal overload relay, 50 A/1000 V, thermal setting range 37 to 50 A, tripping class 10 A, for protection of 3 PH motors 22 kW at 400 V. Differential device with phase failure and load unbalance detection. It provides a thermal adjustment dial, a manual automatic reset selector acting also as reset button a trip test button for simulation of a tripping, a stop button a flag indicator and 2 auxiliary contacts 1 NO plus 1 NC for fault signaling. Settings are protected by a transparent cover lockable by sealing. Connection by screw clamp terminals, it connects directly to the bottom terminals of three-pole contactors LC1D80-D95. Mounting on DIN rail or screw fixing, separated from the contactor, with use of a terminal block LA7D3064 (to be ordered separately).
