The Schneider Electric LAD9V1 is an electrical interlock accessory designed for TeSys D reversing and changeover contactor applications. This component facilitates safe operation by ensuring that only one contactor in a reversing or changeover pair can be energized at a time, preventing short circuits and equipment damage. It is specifically engineered to work with TeSys D contactors in the LC1D09 through LC1D38 series, as well as the LC1DT20 through LC1DT40 reversing contactor series.

Technical details

• Series: TeSys D
• Accessory Type: Electrical Interlock
• Functionality: Reversing and Changeover Control
• Compatible Contactor Series (Standard): LC1D09, LC1D12, LC1D18, LC1D25, LC1D32, LC1D38
• Compatible Contactor Series (Reversing): LC1DT20, LC1DT30, LC1DT40
• Mounting Type: Front-mounted
• Contact Configuration: Typically includes normally closed (NC) contacts for interlocking purposes. Specific contact count and type should be verified against the manufacturer's datasheet.
• Voltage Rating: The voltage rating for the interlock contacts themselves should be confirmed via the manufacturer's datasheet, as it is not explicitly encoded in the LAD9V1 part number.

Applications & compatibility

This electrical interlock is essential for applications requiring motor reversing or changeover functionality, such as in packaging machinery, material handling systems, and HVAC equipment. It ensures reliable and safe operation of motor control circuits where directional control is critical, preventing simultaneous energization of opposing contactors in reversing starter configurations.
