Description
The TeSys LRD22 is a reliable thermal overload relay designed for the protection of 3-phase motors up to 11 kW at 400V. With a thermal setting range of 16–24A and tripping class 10A, this relay offers precise motor protection against overloads, phase failures, and load imbalance.
Ideal for use with TeSys D contactors (LC1D25 to LC1D38), it can be directly mounted or separated with the optional LAD7B106 terminal block. Its intuitive design includes a manual/automatic reset selector, test function, fault flag, and 1NO+1NC auxiliary contacts for trip indication.
Certified to global standards (IEC, UL, CSA, CCC, EAC, ATEX, Marine) and compliant with Green Premium (RoHS/REACH), the LRD22 is built for high performance and sustainability in industrial motor control applications.
