✅ Schneider Electric LA9D80978 – Mechanical Interlock for LC1D80–D95 DC Contactors Part No.: LA9D80978 The Schneider Electric LA9D80978 is a mechanical interlock unit designed specifically for TeSys D contactors LC1D80 to LC1D95 with DC coils. This interlock ensures the mechanical blocking of one contactor when the other is energized, thus preventing simultaneous operation of both contactors in a reversing or changeover circuit. Ideal for use in safety-critical motor control applications, this interlock enhances system reliability by ensuring that only one contactor can close at a time. 🔧 Technical Specifications Attribute Details Product Type Mechanical Interlock Series Compatibility TeSys D Part Number LA9D80978 Compatible Contactors LC1D80–D95 with DC coil Function Prevents simultaneous closure of two contactors Application Reversing starters, changeover motor control Mounting Type Between two horizontally mounted contactors Compliance CE, RoHS, REACh, Green Premium 📦 Packaging & Installation Unit Type: Mechanical Interlock Mounting Orientation: Horizontal Easy Integration: Fits between contactor bodies without additional tools 🔩 Applications: Designed for reversing motor starters or systems requiring mechanical interlocking between LC1D80–D95 DC contactors, where safe mutual exclusion is critical.
