OVER CURRENT RELAY TESYS 20-38A 24V AC/DC LR97D38B

TeSys LR97D Electronic Overcurrent Relays 0.3 - 38 A Features: - Direct mounting on TeSys D contactor output (<38 A, LC1D38), width 45 mm - Screw / tunnel connection - External supply voltage 24-230 V AC - Manual or automatic reset - Protection functions: - Overcurrent due to overload or mechanical seizure: monitoring of excess torque during starting and continuous operation - Protection against torque peaks - Protection against locked rotor - Protection against phase failure. - Current threshold setting with two separate time settings (trip during starting and trip during continuous operation) - Selection of 3- or 1-phase operation - Diagnostics with two LEDs (starting, excess torque, locked rotor, phase failure) - Auxiliary contact: 1 changeover contact (C/O). Benefits: Machine protection integrated with the motor starter. Thanks to simple setting and signaling features, the electronic overcurrent relay or torque relay ensures optimal machine protection. Its compact size (width 45 mm) makes it easy to integrate with the motor starter. Applications: Industry, infrastructure, buildings: - Machines with high resistive torque - Machines with high inertia - Machines with high risk of seizure during continuous operation These relays have no thermal memory and are suitable for protecting motors in demanding applications: - Machines with long starting times - Machines frequently started.
