TeSys Lt47

TeSys LT47 electronic overcurrent relays memberikan perlindungan terhadap rotor yang terkunci, kejang, atau guncangan mekanis. Berbeda dengan relai kelebihan beban termal, relai ini tidak memiliki memori termal. Mereka memiliki karakteristik waktu yang pasti dengan ambang arus yang dapat disesuaikan dan waktu tunda.

Fitur Utama

DIN rail or plate mounting
Screw clamp or lug connections
External 24 to 230 V AC power supply
Manual or automatic reset depending on model.
Protection functions:

- 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.

Keuntungan

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.
