Features
- 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 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.
Benefits
- 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.
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.
