## Long description

The Schneider Electric LADT4 is a high-quality auxiliary contact block specifically engineered for integration with TeSys contactors. This modular component is designed to provide precise time delay functionality, offering a range between 10 and 180 seconds to meet the requirements of complex industrial automation systems. With its robust construction and reliable 1 NO and 1 NC contact configuration, it serves as an essential element for managing switching sequences in electrical control panels.
Advantages
The primary benefit of the Schneider Electric LADT4 is its ability to provide accurate and repeatable time-delayed switching, which is critical for protecting sensitive equipment and managing motor start-up sequences. Its compact design allows for easy installation within existing control cabinets, while the wide operating temperature range ensures consistent performance even in demanding industrial environments. The inclusion of both normally open and normally closed contacts offers versatile wiring options for various control logic requirements.
Suitable for
Industrial motor control systems
Automation processes requiring sequential switching
Time-dependent safety interlocks
Electrical control panels for machinery
When it may not be suitable
This auxiliary contact block is specifically designed for use with compatible TeSys contactors and may not be compatible with contactors from other manufacturers or different product series. It is not intended for applications requiring timing intervals shorter than 10 seconds or longer than 180 seconds.
Key specifications
Time delay range: 10 to 180 seconds
Contact configuration: 1 NO and 1 NC
Operating temperature: -40 to 70 °C
Dimensions: 44 mm width, 61 mm depth, 48 mm height
Colour: White
How to use
The LADT4 contact block is designed for front-mounting onto compatible TeSys contactors. Before installation, ensure that the power supply to the contactor is disconnected to prevent accidental activation. Align the block with the mounting interface on the contactor and snap it into place until it is securely seated. Once installed, adjust the timing dial on the front of the unit to the desired interval within the 10 to 180-second range. Verify the wiring connections to the NO and NC terminals according to your specific control circuit diagram before restoring power.
What to consider before purchase
Verify compatibility with your specific TeSys contactor model
Ensure the required timing interval falls within the 10–180 second range
Check available space in the control cabinet for the 44 mm x 61 mm x 48 mm dimensions
Confirm that the environmental temperature remains within the -40 to 70 °C operating range
Usage recommendations
Always perform a functional test of the time delay sequence after installation and before putting the machinery into full operation to ensure the timing matches the intended control logic.
