Product Description
The Telemecanique LA6DK3 is a high-performance mechanical latching attachment designed to lock a contactor in the "ON" position without requiring continuous power to the contactor coil. This "memory" function is essential for energy-saving circuits, critical power maintenance, and applications where a voltage drop would otherwise cause the contactor to drop out.
While originally part of the Telemecanique "D2" legacy series, the LA6DK3 remains a vital replacement part for maintaining older industrial control panels. It features a manual override for testing and a rugged mechanical life of 500,000 cycles, ensuring long-term reliability in demanding environments.

Key Features & Benefits
-
Energy Efficiency: Once latched, the main contactor coil can be de-energized, significantly reducing power consumption and heat generation within the control panel.
-
Fail-Safe Operation: Holds the contactor in the closed position even during total power loss or control circuit fluctuations.
-
Manual Override: Equipped with a manual tripping mechanism to allow for maintenance testing and system commissioning without electrical pulses.
-
Industrial Durability: Designed for high-frequency switching, capable of handling up to 1,200 cycles per hour for heavy-duty automation.
-
Compact Integration: Clips directly onto the front of the contactor, maintaining a narrow profile to save valuable DIN rail space.
