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.
Benefits
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.
Applications
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.
