Schneider Electric LR9D5369 TeSys LRD thermal overload relays 90-150A Class 10 for NSX circuit breaker
Product Description
The Schneider Electric LR9D5369 is a high-performance Class 10 thermal overload relay from the TeSys LR9D family, engineered to protect three-phase asynchronous motors against overload, phase-loss and unbalanced currents. Rated for 90–150 A at 690 V AC, it delivers precise trip timing, manual and automatic reset options, and direct DIN-rail or contactor mounting for fast panel integration.
Key Specifications
• Rated Current Range: 90–150 A (adjustable dial)
• Trip Class: 10 (±10 % tolerance)
• Insulation Voltage: 690 V AC (pollution degree 3)
• Breaking Capacity: 100 kA @ 690 V with appropriate contactor
• Ambient Temperature: –20 °C … +60 °C (no derating up to 40 °C)
• Reset Mode: Manual (blue button) or automatic selector
• Auxiliary Contacts: 1 NO (95-96) + 1 NC (97-98) as standard
• Mounting: Clip-on to LC1D series contactors or standalone 35 mm DIN rail (LA7D3064 bracket)

Typical Applications
• Centrifugal pumps & compressors
• Conveyor belts and material handling systems
• HVAC fan motors (110 kW / 150 HP @ 400 V)
• Retrofits replacing LR1D/LR9D older versions
Benefits
• Space-saving: Same footprint as LC1D contactors reduces panel depth
• Reliability: Bi-metal strip technology ensures repeatable trip curves
• Safety: IP20 finger-safe terminals and clear trip indication window
• Maintenance: Tool-free reset and test button for rapid diagnostics
