Thermal overload relay 23-32A, for contactor D32-D38 LRD32

Motor and Circuit Protection – Reliability in Every Detail

The LRD32 thermal overload relay is a key element in protecting electrical installations and motors. Designed by Schneider Electric, it provides effective protection against overload, phase failure and other irregularities that can lead to damage and downtime. Compatible with TeSys Deca series contactors (D32-D38), it is an integral part of control and protection systems.

Functionality and Application

The LRD32 relay is designed for direct mounting, simplifying installation and minimizing space. Its current setting range (23…32 A) allows it to be adapted to a variety of applications and loads. It has a built-in reset button, allowing manual reset after activation, as well as an automatic reset function, increasing ease of use. Thanks to the 10A release class, it provides a quick response to overloads, protecting sensitive components.

• Versatile application: ideal for protecting electric motors, transformers and other devices exposed to overloads.
• Simple installation: direct mounting on the contactor eliminates the need for additional mounting elements.
• Flexibility: the current setting range allows precise adjustment to specific loads.
• Built-in auxiliary contacts: one normally open (1NO) and one normally closed (1NC) contact facilitate integration with control and signaling systems.
• Safety: phase failure protection minimizes the risk of motor damage in the event of a power failure.

Construction and Parameters

The LRD32 relay is characterized by a solid construction and high quality workmanship. It has a screw connection of the main contacts, ensuring secure and durable electrical connections. The maximum rated operating voltage is 690 V AC, which guarantees safety of use in a wide range of industrial applications. Additionally, the lack of the need for additional reset signal inputs simplifies system configuration. The device meets the stringent safety and quality standards of Schneider Electric, confirming its reliability and durability.
