Product Description
It protects 3-phase motors of 55 to 75 kW at 400 V, provides phase-unbalance detection and self-powered operation, and connects directly to LC1D115 and LC1D150 contactors. With manual test and reset, a trip flag indicator and 1 NO + 1 NC signalling contacts, it is a precise, energy-efficient motor-protection device. The Schneider Electric LR9D5369 is a TeSys LR9D electronic thermal overload relay with a thermal setting range of 90 to 150 A and selectable Class 10 / 10A tripping.
Basic Product Information
- Phase-unbalance (differential) detection for reliable motor protection
- Self-powered, no external supply needed; 90% less energy dissipation than thermal relays
- Manual test and reset, trip flag indicator, 1 NO + 1 NC signalling contacts
- Electronic thermal protection, 90 to 150 A range, selectable Class 10 / 10A
Technical Specifications
Version & Model Difference
- ['The LR9D5369 is the 90 to 150 A electronic version for LC1D115/LC1D150; lower-current TeSys LR9D frames cover smaller motors, and the LR9K/LR9F lines address other power ranges.']
Application Scenarios
- Motor protection for 55 to 75 kW 3-phase motors at 400 V
- Industrial automation requiring precise, temperature-compensated tripping
- Applications where reduced heat dissipation vs thermal relays is valued
- No. The LR9D5369 is self-powered (17 to 32 V DC derived internally) and needs no separate supply.
