SKU: LR2K0321 Category:

TeSys LRK thermal overload relay, 14A/690V, thermal setting range 10-14A, tripping class 10A, for protection of 3-phase motors 5.5kW@400V. Differential device with phase failure and load unbalance detection. It provides a thermal adjustement dial, a manual-automatic reset selector, a test slide switch for simulation of a tripping, reset/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 LC1K12-K16. Mounting on DIN rail, separated from the contactor, with use of a terminal block LA7K0064 (to be ordered separately). Multi standards certified (IEC, UL, CSA, CCC, EAC), Green Premium compliant (RoHs/Reach).
