Product Description
- TeSys LRD thermal overload relay, 120A/1000V, thermal setting range 95-120A, tripping class 10A, for protection of 3-phase motors 55kW@400V.
- Differential device with phase failure and load unbalance detection.
- It provides a thermal adjustement dial, a manual-automatic reset selector acting also as reset button, a trip test button for simulation of a tripping, a 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 LC1D115-D150.
- Mounting on DIN rail or screw fixing, separated from the contactor, with use of a terminal block LA7D3064 (to be ordered separately).
- Multi standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine),
Key Features
- Ensure high safty with phase failure and load unbalance detection
- The thermal adjustement dial enables accurate and reliable operation
- It is designed with a transparent cover lockable by sealing in case of misoperation
- Simple mounting on DIN rail or screw fixing
- Sustainability compliant
