Information About LR9F5571
The LR9F5571 belongs to the Schneider Electric TeSys LRF range of electronic motor protection relays designed for high-power contactor assemblies. It is compatible with TeSys F contactors, including LC1F185, LC1F225, and LC1F265, and supports motor protection applications up to 90–110 kW at 400 V. Its electronic protection system monitors current conditions and responds to overloads, phase loss, phase imbalance, prolonged starting times, and stalled rotor conditions. The front control panel incorporates an adjustable current dial, test and stop buttons, manual reset, trip indication, and auxiliary contacts for integration into industrial control circuits.
Key Features:
-
Electronic Overload Protection: Monitors motor current and provides protection against excessive electrical loads.
-
Adjustable Current Range: Supports thermal protection settings from 132 to 220 A.
-
Class 20 Tripping: Provides Class 20 overload response characteristics.
-
Phase Failure Protection: Detects phase loss and abnormal phase conditions.
-
Phase Imbalance Protection: Helps protect motors against unequal phase currents.
-
Contactor Compatibility: Designed for TeSys F contactors LC1F185, LC1F225, and LC1F265.
-
Auxiliary Contacts: Includes 1 normally open and 1 normally closed contact.
-
Manual Reset and Testing: Features front-mounted test, stop, and reset controls with trip indication.
The LR9F5571 delivers the reliability and precision required for industrial motor overload protection and three-phase electrical control systems.
