  • 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:

  • Over currents due to overload or mechanical jamming: starting and steady state operation over torque 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, over torque, 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 over current relay, or over torque 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.
