Product Overview

The Electrihub presents the Schneider Electric LRD12 TeSys Deca Thermal Overload Relay, an essential component for robust motor protection in industrial applications. Engineered for 3-phase motors up to 3kW at 400V, this relay offers a precise thermal setting range of 5.5-8A with a tripping class 10A. Featuring a differential device with phase failure detection, the LRD12 ensures enhanced operational safety and equipment longevity. Its design facilitates direct integration with TeSys Deca 3-pole contactors (LC1D09-D38) via screw clamp terminals, providing a reliable and streamlined solution for motor control circuits.

Key Features

  • Adjustable Thermal Protection: Offers a precise thermal setting range of 5.5-8A with a Class 10A tripping characteristic for effective motor overload protection.
  • Phase Failure Detection: Incorporates a differential device to detect and protect against phase loss, safeguarding motors from critical damage.
  • Flexible Control Options: Equipped with a manual-automatic reset selector, a test selector for trip simulation, and dedicated reset/stop buttons for operational flexibility.
  • Integrated Auxiliary Contacts: Includes 1 NO (Normally Open) and 1 NC (Normally Closed) auxiliary contacts, providing essential fault signaling capabilities for system integration.
  • Seamless Contactor Integration: Designed with screw clamp terminals for direct, tool-free connection to the bottom terminals of Schneider Electric TeSys Deca LC1D09-D38 contactors.

Applications

  • Protection of 3-phase AC motors in various industrial machinery.
  • Integration into motor control centers (MCCs) and control panels.
  • Safeguarding pumps, fans, compressors, and conveyor systems.
  • Use in HVAC systems for motor overload and phase loss protection.
  • General industrial automation requiring reliable motor circuit protection.

Benefits

  • Enhanced Motor Longevity: Provides reliable protection against thermal overloads and phase failure, extending the operational life of industrial motors.
  • Improved System Reliability: The Class 10A tripping ensures rapid response to overload conditions, minimizing downtime and production interruptions.
  • Simplified Troubleshooting: Auxiliary contacts and a flag indicator offer clear fault signaling, enabling quick identification and resolution of issues.
  • Flexible Installation: Can be mounted directly to compatible contactors or separately on a DIN rail/screw fixed with an optional terminal block.
  • Global Compliance: Multi-standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine), ensuring suitability for diverse international industrial environments.
