Schneider TeSys LRD K Series Thermal Overload Relays

Schneider TeSys LRD K Series Thermal Overload Relays Suppliers, Exporters in India

Schneider TeSys LRD K Series Thermal Overload Relays are compact motor protection relays designed to safeguard three-phase AC motors against overload, phase failure, and excessive current conditions. Built for use with Schneider TeSys K contactors, the LRD K Series offers reliable motor protection in applications where panel space is limited and compact motor starters are required.

The relays use thermal overload technology to monitor motor current and disconnect the circuit when overload conditions persist beyond the permitted limit. An adjustable current setting allows the relay to be matched to the motor’s full-load current, ensuring dependable protection without unnecessary tripping.

Designed for easy installation and maintenance, the TeSys LRD K Series features front-mounted adjustment controls, manual or automatic reset selection, and a built-in trip indication. Its compact construction makes it suitable for OEM machinery, control panels, and industrial equipment where reliable motor protection is essential.
