## Summary description

The LSiS UR-02 mechanical interlock is designed for MC-9b-150a contactors. This device ensures safe operation by preventing simultaneous closure of two contactors, providing a reliable interlocking solution for motor control and power switching systems. It is a robust component essential for maintaining electrical safety and operational integrity in industrial automation and control panel configurations.

## Long description

The LSiS UR-02 mechanical interlock is a precision-engineered safety device specifically designed for use with LSiS MC-9b through MC-150a contactors. This component serves as a critical safeguard in electrical control systems by physically preventing the simultaneous closure of two contactors. By ensuring that only one contactor can be engaged at any given time, it effectively eliminates the risk of short circuits caused by overlapping phases, thereby protecting your equipment and enhancing the overall reliability of your power switching configurations.
Advantages
The primary benefit of the LSiS UR-02 is its robust mechanical design, which provides a fail-safe interlocking mechanism that does not rely on electrical signals or software logic. This physical barrier ensures maximum operational safety in demanding industrial environments. Its compact construction allows for easy integration into existing control panels without requiring significant additional space. Furthermore, the device is built to withstand the mechanical stresses of frequent switching operations, ensuring long-term durability and consistent performance in motor control applications.
Suitable for
Reversing motor starter configurations
Changeover switching systems for power supplies
Industrial automation control panels
Motor control centers requiring safety interlocks
When it may not be suitable
This mechanical interlock is exclusively compatible with the specified LSiS contactor series. It cannot be used with contactors from other manufacturers or different product lines. Additionally, it is not intended for applications requiring electrical interlocking or remote monitoring capabilities.
Key specifications
Compatibility: LSiS MC-9b to MC-150a contactors
Mechanism: Mechanical physical interlock
Function: Prevents simultaneous contactor closure
Application: Industrial motor control and power switching
How to use
Installation of the UR-02 interlock involves mounting the device between two adjacent contactors. Ensure that the power supply to the contactors is completely disconnected before beginning the installation process. Align the interlock mechanism with the designated mounting points on the contactors and secure it firmly according to the mechanical guides. Once installed, manually test the operation by attempting to engage both contactors simultaneously to verify that the mechanical block prevents both from closing at the same time.
What to consider before purchase
Verify that your contactor models fall within the MC-9b to MC-150a range
Ensure there is sufficient physical space on the DIN rail or mounting plate for the interlock assembly
Confirm that the application requires a physical mechanical block rather than an electrical one
Usage recommendations
Always perform a functional test after installation to ensure the interlocking mechanism operates smoothly and prevents simultaneous engagement before putting the system into full operation.
