TeSys Deca differential thermal overload relay 62-80A class10A for lugs
TeSys LRD thermal overload relay, 80A/690V, thermal setting range 62-80A, tripping class 10A, for protection of 3-phase motors 37kW@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 EverLink BTR screw terminals , it connects directly to the bottom terminals of 3-pole contactors LC1D40A-D80A. Mounting on DIN rail or screw fixing, separated from the contactor, with use of a terminal block LAD96560 (to be ordered separately). Multi standards certified (IEC, UL, CSA, CCC, EAC, Marine), Green Premium compliant (RoHs/Reach).
