TeSys LRD
electronic overload relay for motor TeSys - 0.3...1.5 A - 24 V AC/DC.Label:TeSys LR97D-thermal protection adjustment range:0.3-1.5 A-device short name:LR97-product or component type:electronic overcurrent relay-device application:protection-relay application:locked rotor, mechanical jamming I 3 x Isetting,sensitivity to phase failure,overload Imax Isetting-quantity per set:set of 10-product compatibility:LC1D09...D38-network type:DC,AC-Range Presentation:
- 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 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.-Range Benefits:Machine protection combined with motor starter
With its simple setting and signalling features, the electronic over current 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.-Range Application Presentation: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.
