Schneider Electric LAD9R1V Mechanical Interlock for LC1D09-D38 Contactors

The Schneider Electric LAD9R1V mechanical interlock is a precision-engineered safety accessory designed specifically for TeSys D contactors ranging from LC1D09 to LC1D38. This device serves as a critical component in industrial control systems, providing a robust mechanical barrier that prevents two contactors from closing simultaneously. By ensuring that only one contactor can be active at any given time, it effectively eliminates the risk of short circuits in reversing starter configurations, thereby enhancing the operational safety and longevity of your electrical equipment.

Advantages

The primary benefit of the LAD9R1V interlock is its ability to provide reliable, fail-safe mechanical protection without the need for complex electrical wiring. Its compact design allows for seamless integration directly between two contactors, saving valuable space within control panels. Manufactured by Schneider Electric, this component is built to meet high industrial standards, ensuring consistent performance and durability even in demanding environments. The installation process is straightforward, allowing for quick assembly and maintenance of motor control circuits.

Suitable for

• Reversing starter applications
• Motor control centers
• Industrial automation systems
• Electrical panels requiring interlocking contactors

When it may not be suitable

This mechanical interlock is specifically designed for the TeSys D series contactors from LC1D09 to LC1D38. It is not compatible with contactors outside of this specific range or from different product series. It should not be used as a substitute for electrical interlocking in applications where redundant safety measures are required by specific local regulations.

Key specifications

• Compatibility: TeSys D contactors LC1D09 to LC1D38
• Weight: 45 g
• Package weight: 70 g
• Package depth: 25 mm
• Quantity: 1 piece per pack

How to use

To install the LAD9R1V, ensure that the power supply to the contactors is completely disconnected. Position the mechanical interlock between the two contactors intended for the reversing starter circuit. Align the device according to the manufacturer's mounting instructions, ensuring it clicks securely into place. Once installed, manually test the operation by attempting to engage both contactors simultaneously to verify that the mechanical lockout prevents them from closing at the same time. Only after successful verification should the system be re-energized.

What to consider before purchase

• Verify that your contactor models fall within the LC1D09 to LC1D38 range.
• Ensure there is sufficient physical space between the contactors for the interlock installation.
• Confirm that your application requires a mechanical rather than an electrical-only interlock.

Usage recommendations: Always perform a manual mechanical test after installation to ensure the interlock is functioning correctly before applying electrical power to the circuit.
