- Overcurrents due to overload or mechanical jamming: starting and steady state operation overtorque monitoring. - Can be used as torque surge protection.
Current threshold adjustment using 2 separate time settings (starting and trip in steady state operation)
2 LED indicators (starting and overtorque).
Auxiliary contacts: 1 N/C + 1 N/O
Looped cabling possible when the motor current is less than the minimum setting.
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 it easily integrates in the motor starter functions.
Các ứng dụng
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:
