Thermal relay TeSys LRD

LRD thermal relays prevent overloading and premature ageing of the motor. The thermal relays are supplied with manual setting acknowledgement, but they can also, if needed, be changed to automatic setting acknowledgement. The thermal relay can easily be connected to TeSys D contactors, creating a compact starter solution.
