TeSys LRD thermal overload relays - 17...25 A - class 10A

LRD3322
Image

TeSys LRD thermal overload relay, 25A/690V, thermal setting range 17-25A, tripping class 10A, for protection of 3-phase motors 11kW@400V. Differential device with phase failure and load unbalance detection. 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 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, Marine), Green Premium compliant (RoHs/Reach).
