Schneider Electric TeSys K - differential thermal overload relays - 0.23...0.36 A - class 10A

Rp ‎ 617.200

Description

TeSys LRK thermal overload relay, 0.36A/690V, thermal setting range 0.23-0.36A, tripping class 10A, for protection of 3-phase motors 0.09kW@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).
