It mounts between two EasyPact TVS contactors in the LC1E300 through LC1E500 frame sizes, enforcing a 3-pole mechanical interlock that is essential for reversing drives, star-delta starters, or any circuit where simultaneous closure would create a phase-to-phase short. The mechanical interlock type means there is no electrical sensing or solenoid — it is a purely mechanical bar that slides between the contactor armatures. One contactor closes, the bar shifts, and the other contactor's armature is physically blocked. This is the standard method for reversing or two-speed motor starters where a direct electrical interlock alone is not fail-safe against welded contacts.
As a mechanical interlock accessory, the LAEM7 is typically quoted to order against a BOM line rather than held on the shelf in high volume. Confirming fit against the specific contactor frame (LC1E300 through LC1E500) before placing the RFQ avoids a mismatch — the interlock bar length and mounting hole pattern change with contactor frame size.
Integration notes
The LAEM7 clips onto the contactor mounting feet without additional hardware. The interlock bar engages with the moving contact carriers of both contactors, so the contactors must be aligned vertically and the bar must slide freely before the assembly is tightened down.
