TeSys LR97D - Electronic overcurrent relays 0,3 A to 38 A

    Direct mounting beneath TeSys Model d contactors up to LC1D38, width 45 mm
    Screw clamp or lug connections
    External 24 to 230 V AC power supply
    Manual or automatic reset
    Protection functions:
    - Overcurrents due to overload or mechanical jamming: starting and steady state operation overtorque monitoring - Can be used as torque surge protection
    - Specific protection for locked rotor
    - Specific protection for phase failure.
    Current threshold adjustment using 2 separate time settings (starting and trip in steady state operation)
    Selection of 3-phase or single-phase operation
    Diagnostics via 2 LED indicators (starting, overtorque, rotor locked and phase failure)
    Auxiliary contact: 1 C/O.


Machine protection combined with motor starter
With its simple setting and signalling features, the electronic overcurrent relay, or overtorque protection relay, assures optimal protection of your machine.
Due to its compactness  (45 mm wide) it easily integrates in the motor starter functions.

Industry, infrastructures, buildings:

    Machines with high resistive torque
    High inertia machines
    Machines with high risk of jamming during steady state operation.

These relays do not have thermal memory and can be used as specific motor protection in the case of severe duty applications:

    Machine with long starting time
    Machine with frequent starting.
