TeSys Deca LRD thermal overload relay, 32A/1000V, thermal setting range 23-32A, tripping class 10A, for protection of 3-phase motors 15kW@400V. Differential device with phase failure (loss). It provides a thermal adjustement 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 1NO+1NC for fault signalling. Settings are protected by a transparent cover lockable by sealing. Connection by screw clamp/ lugs-ring terminals, it connects directly to the bottom terminals of 3-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). Multi standards certified (IEC, UL, CSA, CCC, EAC, ATEX).
