    Description

    TeSys LRD thermal overload relay, 65A/690V, thermal setting range 48-65A, tripping class 10A, for protection of 3-phase motors 30kW@400V. Differential device with phase failure and load unbalance detection. It provides a thermal adjustement dial, a manual-automatic reset selector, a test selector for simulation of a tripping, reset and stop buttons, a flag indicator and 2 auxiliary contacts 1NO+1NC for fault signalling. Settings are protected by a transparent cover lockable by sealing. Connection by EverLink BTR screw terminals , it connects directly to the bottom terminals of 3-pole contactors LC1D40A-D80A. Mounting on DIN rail or screw fixing, separated from the contactor, with use of a terminal block LAD96560 (to be ordered separately). Multi standards certified (IEC, UL, CSA, CCC, EAC, Marine), Green Premium compliant (RoHs/Reach).

    Features

    • Featuring a precise, integrated current adjustment dial spanning 48 to 65 Amps, this relay allows facility electricians to calibrate motor protection to exact nameplate ratings. This precise fine-tuning prevents frequent nuisance trips during heavy machine startup cycles while ensuring reliable overcurrent protection for demanding industrial pumps, fans, and shredders.
    • Operating on a proven Class 10A trip curve, this relay is engineered to disconnect power within 10 seconds of experiencing a locked-rotor or heavy 600% overload condition. This standardized performance balance delivers highly responsive protection for general-purpose industrial equipment while easily tolerating normal high-inrush currents during initial motor acceleration.
    • Designed with a transparent, sealable protective cover, this unit physically locks your specific current parameters to prevent accidental movement or unauthorized manipulation. Paired with explicit stop and manual/auto-reset buttons, an integrated trip-test mechanism, and 1NO+1NC built-in auxiliary contacts, it provides seamless fault signaling and highly predictable maintenance workflows.
