Thermal overload relay TeSys LRD 0.4-0.63A screw terminals LRD04

Motor and Circuit Protection with TeSys LRD 04 Overload Relay

This TeSys LRD 04 overload relay, with a setting range of 0.4 – 0.63 A, is a reliable solution for protecting motors and circuits from overload. Designed to work with TeSys Deca series contactors, it provides comprehensive protection against various failures, including phase loss and excessive starting time. This ensures the installation is safe and efficient, and the risk of damage is minimized.

Application and functionality

The LRD 04 relay protects against the effects of overload, which can lead to overheating and damage to the motor or wires. Its design based on class 10A release guarantees a precise response to irregularities in the circuit. Automatic reset allows the installation to be restarted after the cause of the trip is removed (in the case of automatic reset), minimizing downtime. Additionally, manual reset allows full control over the restart process.

Key features for installers and users
