The LR2D13 Series Electronic Overcurrent Relay is designed to provide accurate and dependable protection for electric motors against overload and phase failure conditions. Engineered for compatibility with contactors, this relay is widely used in motor control circuits across industrial and commercial environments.
With an adjustable current setting range, the LR2D13 allows precise configuration according to motor requirements, ensuring optimal protection performance. The relay operates using advanced thermal/electronic sensing to detect overload conditions and automatically disconnect the circuit before damage occurs.
Its compact design enables easy installation, either directly mounted onto contactors or on DIN rails, making it ideal for panel builders and automation systems. The inclusion of both normally open (NO) and normally closed (NC) auxiliary contacts allows for flexible integration into control and alarm circuits.
The LR2D13 also features phase failure sensitivity, helping protect motors from damage caused by voltage imbalance or phase loss—common issues in industrial systems.
Typical Applications:
Motor protection circuits
Industrial automation panels
Pumps and compressors
HVAC systems
Manufacturing equipment
Reliable, compact, and easy to install, the LR2D13 Series is a cost-effective solution for ensuring motor safety and extending equipment lifespan.
