Thermal overload relay, TeSys Deca, 17-25A, class 10, screw terminals LRD325

Thermal overload relay TeSys Deca LRD325 is a reliable device used to protect electric motors against overload. Designed to work with TeSys Deca contactors, it provides effective protection in demanding industrial conditions. Its current setting range of 17-25A makes it a versatile solution for various applications.

Protection and functionality

The LRD325 relay protects motor circuits not only against overload, but also against phase failure and excessively long starting times. Thanks to its Class 10A trip characteristic, it provides a quick and precise response to motor malfunctions. Automatic reset allows the circuit to be restarted after the cause of the trip has been removed, while the possibility of manual reset provides additional control over the process. It has one normally open and one normally closed auxiliary contact, allowing for trip status signaling and remote control.

Mounting and compatibility

The relay is designed for direct mounting on TeSys D40A-D65A contactors, minimizing space and simplifying installation. The possibility of independent mounting using additional accessories (e.g., rails) increases application flexibility. The connection of the main contacts is made using screw connections, ensuring a secure and durable connection of the wires. The power supply is AC or DC up to 690V.

Additional features and benefits

• Status indication: Built-in trip indicator relay and the ability to connect optical signaling inform about the device's operating status.
• Temperature compensation: Ensures accurate operation over a wide range of ambient temperatures (-20°C to +60°C).
• Safety: Compliance with IEC 60947-4-1 standards guarantees safe use and reliable operation.
• Durability: Made of high-quality materials, ensuring a long service life even in harsh industrial conditions.
• Ease of use: Intuitive reset button makes it easy to restore circuit operation after removing the cause of the trip.
• Versatility: Can be used in both AC and DC applications.
• Status indicator: Has a trip indicator flag that visually informs about the activation of the protection.
