Schneider Electric, TeSys K - differential thermal overload relays - 5.5...8 A - class 10A
Range: TeSys
Product type: Differential thermal overload relay
Relay application: Motor protection
Network type: DC, AC
TeSys LRK thermal overload relay,8A/690V,thermal setting range 5.5-8A,tripping class 10A,for protection of 3-phase motors 3kW@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 LC1K09-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).
