Product Description
- TeSys LRK thermal overload relay, 11.5A/690V, thermal setting range 8-11.5A, tripping class 10A, for protection of 3-phase motors 4kW@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),
Key Features
