Description

LR3D21 is a TeSys LRD thermal overload relay from Schneider Electric to be used with a TeSys D contactor. It protects motors 7.5kW@400V thanks to a thermal range 12-18A , a tripping class 10A, for use with unbalanced loads. LR3D21 is a TeSys LRD thermal overload relay from Schneider Electric for direct mounting on TeSys D contactors. With a thermal setting range 12-18A and tripping class 10A, it protects unbalanced loads and motors 7.5kW@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 LC1D18-D38 to form a compact starter. Light and compact, 45mm 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).
