Product Data Sheet
TeSys LRD thermal overload relay, 4A/690V, thermal setting range 2.5-4A, tripping class 20, for protection of 3-phase motors 1.1-1.5kW@400V. Differential device with phase failure and load unbalance detection. 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 3-pole contactors LC1D09-D38. Mounting on DIN rail or screw fixing, separated from the contactor, with use of a terminal block LAD7B105 (to be ordered separately). Multi standards certified (IEC, UL, CSA, Marine), Green Premium compliant (RoHS/REACh).
