Overview
Details for LR9D08
TeSys LRD, Electronic thermal overload relay, 3P, 0.6...8 A
LR9D08 is a TeSys LR9D electronic overload relay from Schneider Electric to be used with a TeSys D contactor. With a thermal range 1.6-8A, selectable tripping class 5-10-20-30 and phase unbalance protection, it protects motors 1.1 to 2.2kW@400V. LR9D08 is a TeSys LR9D electronic overload relay from Schneider Electric for direct mounting on TeSys D contactors. With a large thermal setting range 1.6-8A, a selectable tripping class 5-10-20-30 and phase unbalance detection, it protects motors 1.1 to 2.2kW@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, electronic type, with phase unbalance protection (differential), self powered (no external power supply needed). Direct mounting on the bottom terminals of a Tesys LC1D09-D38 to form a compact starter contactor. Light and compact, 45mm wide. Manual control with test & reset buttons, manual / automatic reset selector. High accuracy, temperature compensated to keep a precise tripping over the ambient temperature range. Wide protection adjustment range 1.6-8A and selectable tripping class 5-10-20 -30. Trip signaling with 1NO+1NC auxiliary contacts and trip flag indicator. 90% reduction in energy dissipation compared to a thermal overload relay. Can be completed with terminal blocks and separate mounting accessories (LAD7B).Specifications
