TeSys LRD thermal overload relay, 1A/690V, thermal setting range 0.63-1A, tripping class 10A, for protection of 3-phase motors 0.25-0.37kW@400V. Differential device with phase failure and load unbalance detection. It provides a thermal adjustment dial, a manual-automatic reset selector, a test selector for simulation of tripping, reset and stop buttons, a flag indicator, and 2 auxiliary contacts 1NO+1NC 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 3-pole contactors LC1D09-D38. Mounting on DIN rail or screw fixing, separated from the contactor, with the use of a terminal block LAD7B106 (to be ordered separately).
