Schneider TeSys LRE Series Electronic Overload Relays

Schneider TeSys LRE Series Electronic Overload Relays Suppliers, Exporters in India

Schneider TeSys LRE Series Electronic Overload Relays are electronic motor protection relays designed to protect three-phase AC motors against overload, phase loss, phase imbalance, and prolonged overcurrent conditions. The series offers greater accuracy than conventional thermal overload relays, making it suitable for applications where consistent motor protection and dependable operation are important.

The TeSys LRE Series continuously monitors motor current and responds quickly to abnormal operating conditions, helping reduce the risk of motor damage and unexpected downtime. With adjustable current settings and electronic trip characteristics, these relays provide stable protection across a wide operating range.

Designed for use with Schneider TeSys contactors, the LRE Series features a compact design that allows easy installation in motor control centres and industrial control panels. Front-mounted controls make configuration simple, while the manual or automatic reset option provides flexibility for different operating requirements.
