LR3D3555 is a TeSys LRD thermal overload relay from Schneider Electric to be used with a TeSys D contactor. It protects motors 18.5kW@400V thanks to a thermal range 30-40A , a tripping class 20, for use with unbalanced loads. LR3D3555 is a TeSys LRD thermal overload relay from Schneider Electric for direct mounting on TeSys D contactors. With a thermal setting range 30-40A and tripping class 20, it protects unbalanced loads and motors 18.5kW@400V. It provides manual test & reset buttons, automatic reset, trip auxiliary contact and flag indicator. Available worldwide, it is multi-standards certified (IEC, UL, CSA, CCC, EAC, Marine) and Green Premium compliant (RoHs/Reach). Thermal overload protection relay, bimetallic type, for use with unbalanced loads (non differential). Direct mounting on the bottom terminals of a Tesys contactor LC1D80 and D95 to form a compact starter. Light and compact, 70mm wide. Temperature compensated for a good accuracy of the protection. Manual control with test & reset buttons, manual / automatic reset selector. Trip signaling with 1NO+1NC auxiliary contacts and trip flag indicator. Can be completed with terminal blocks for separate mounting (LAD7B, LAD96) and remote control devices (LAD703, LA7D03).

The Schneider Electric thermal overload relay is designed to protect ac circuits and motors against overloads. It provides a thermal adjustment dial, a manual-automatic reset selector, a test selector for simulation of a tripping, reset and stop buttons and a flag indicator.
