Frequently Asked Questions
Two lock elements come with LAD311. The first one, already mounted on LAD311 when delivered is suitable for almost all cases of LC1D contactor. However, depending on the type of coil of the contactor (DC or AC), this element shall be mounted in one position for DC or turned by 180° around an horizontal axis for AC coil contactor. Note that on the lateral face of this elements the markings “DC” or “AC” mounted upwards indicates the right position to be used. The second LAD311 lock element shall be used when mounting contactors LC1D09 to LC1D18 with screw clamp. In this case, this element shall be mounted on LAD311 instead of the first one which can be scrapped away.
See attached document for reference.

Difference between Integral Starter and Tesys U
Contactors and Starter - IEC
Tesys U Starter
The dimensions of the U-Line base and the LD1LB are very similar. If they are panel mounted, the upper hole can usually be re-used. The lower one will have to be re-located but not far. The door mounted handles are not interchangeable. The U-Line operator mechanism is LU9AP00 and the handles are LU9AL11 for black and LU9AP12 for red and yellow.
However, the aux contact blocks do not match in quantity and available functionality, so the cross must include all components when comparing U-Line
to Integral lines to arrive at a cross reference. You can never cross components separately and assure equivalence.
