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
- 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:
