Old Price: AED 131.880

New Price: AED 126.750 (4%)

Tesys K thermal overload relays are designed to protect a.c. circuits and motors against overloads.
Simple to select and install at optimized budget
The range delivers strong performance for its compact size and promises seamless integration in all applications.

TeSys LRK thermal overload relay, 0.54A/690V, thermal setting range 0.36-0.54A, tripping class 10A, for protection of 3-phase motors 0.12kW@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 LC1K06-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).
