• Yellow trip indicator gives clear local visual signaling when the relay has operated
• Red test button allows functional verification of the trip mechanism without disconnecting the circuit
• Blue stop button and front selector switch enable either manual or automatic reset after tripping
• Direct under-contactor mounting for LC1K, LC7K, LP4K, and LP1K reduces panel wiring and footprint

Applications:

• Motor overload protection in industrial control panels and machine tools
• Direct-on-line and reversing starter assemblies using TeSys K contactors
• Pump, fan, and compressor protection in building services installations
• Compact OEM motor starters requiring contactor-mounted thermal protection

Compliant with IEC 60947-4-1, NF C 63-650, BS 4941, and VDE 0660. Part of the Schneider Electric TeSys K range.
