LR9D08 Thermal Overload Relay: Precise Protection for Electrical CircuitsThe LR9D08 thermal overload relay from Schneider Electric (Square D) is engineered to provide reliable protection for electrical circuits, preventing damage from overloads and short circuits.
Specifically designed for motor applications, this relay offers precise tripping characteristics within a range of 1.6-8A. Its thermal sensing element accurately detects overloads, ensuring timely disconnection of the circuit before overheating occurs.
The LR9D08 is constructed with robust materials, ensuring durability in demanding industrial environments. Its compact size allows for easy installation in control panels or enclosures.
Key Features:
- Overload protection range: 1.6-8A
- Thermal sensing element for precise tripping
- Compact design for easy installation
- Reliable protection against overloads and short circuits
- Ideal for motor applications

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).
