DIFFERENTIAL THERMAL OVERLOAD RELAYS, TeSys K, 12...16 A, Class 10A

DIFFERENTIAL THERMAL OVERLOAD RELAYS

thermal protection adjustment range : 12…16 A
network type : AC/ DC
auxiliary contact composition : 1 NO + 1 NC
Thermal overload class : Class 10A

TeSys LRK thermal overload relay, 16A/690V, thermal setting range 12-16A, tripping class 10A, for protection of 3-phase motors 7.5kW@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 LC1K16. 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).
